Examples of "regional" common knowledge
August 2, 2016 8:47 AM Subscribe

A family member has been visiting the Chicago suburbs for 15 years and just experienced a tornado siren test for the first time. After recovering, the question was asked, what other things do people do, know, accept, etc. it isn't given a second thought by locals, but would be unexpected, unusual, etc. to outsiders?

Even just looking up information on the sirens, it seems like "civil defense siren" is a more universal term, but we just call them tornado sirens. Totally normal, unless you don't live in an area that has tornadoes.

I've seen things like the regional maps of terms like soda (incorrect) vs. pop (correct), and assume pop culture stuff like everyone in Chicagoland knowing the phone number for Empire Carpet by heart will vary, but what are pieces of "common knowledge" may only be common in a given area?

Not restrained to Chicago or the Midwest or even the US; just looking for examples of things that seem totally normal when you grow up with them, but maybe actually be unique.

"Surface streets" means "not the freeway" in Los Angeles, but I learned after moving away that people in other regions don't use that term.

Traffic lanes which change direction depending on the time of day, which seems insane, except in Nebraska.

I grew up in Vermont. We don't have toll roads. The concept of carrying change for driving didn't enter my naive little mind until I took my first road trip out of state.

Right-of-way at traffic circles in New Jersey is determined by "local custom". Straight out of the driver's manual: "In most cases, the circle’s historically established traffic flow pattern dictates who has the right-of-way."

Massachusetts and other states along the New England coast often issue Red Tide warnings during the warmer months, which was something I had never heard of until I moved here. Red Tide is an algal bloom that can make people sick; swimming and shellfishing are generally restricted when it gets bad.

Military bases will play Reveille in the morning and the national anthem in the afternoon. Reveille is generally ignored, but in the afternoon the whole base comes to a standstill during the national anthem. Cars are expected to stop, pedestrians halt and put hands to hearts and remove hats. None of this is explained to outsiders.

Here in Northeast Florida one of the things that always astonishes visitors is the suddenness and ferocity of afternoon thunderstorms. It'll be sunny one minute, pitch black and raining sideways the next, and then sunny ten minutes later. It's not at all uncommon to see this in your mirror on a daily basis.

Things I find weird when I visit New Jersey:

Many intersections don't allow left turns. You turn left by making a right turn onto a "jug handle" road that curves around and brings you onto the road you want.

You can't pump your own gas. (Also true in Oregon, though I believe now there are some exceptions there.)

funeral processions (not one you're in). the rules are laid out in the driving manual but I never encountered one 'in the wild' until after a decade or so because they are so uncommon where I grew up (suburban L.A.). It took me a while to figure out what was going on and remember the protocol.

Come to think of it, I had the same problem with school busses: I didn't live somewhere where they stop and let kids out by the side of the road until recently.

Just the term you used Chicagoland is a good example. When I moved to Chicago from the Tri-Sate area (NY, NJ, CT) it took me a good two years before I knew wtf people were referring to when they used Chicagoland.

Here in Westchester County you will hear the occasional nuclear power plant evacuation siren tests. I call it the kiss your ass goodbye signal, but I don't think that is the official name for it. Also, you are only expected to evacuate if you are in a 10 mile radius of the plant. I have had visitors asking about the long loud siren that went on for minutes.

I think posted speed limits and actual traffic patterns is another one. I know that on the LIE (495) that 55 really means 70.

There are monthly sirens tests for the Sequoyah Nuclear Power plant in Tennessee - at least there were when I was growing up near it. Also evacuation routes marked on road signs in the area. I assume the same is true for other areas with nuclear plants.

Back in the '90s I was in a building and experienced my first earthquake. I was an a fairly interior office, and it was over fairly quickly, so I only got to the "WTF?!?!" moment, but the folks closer to the exit door started evacuating. One of the non-natives had heard "shelter in doorways" and so, for a brief moment, blocked the exit because reflex told him it was the safest place to be...

In Vermont:

Town meeting. The first Tuesday in March (except in towns that have established a different day for it.) It's where the town's budget for the upcoming year is approved, usually by a voice vote. Various other town government questions may come up for a vote, too - whether to adopt zoning, for instance.

There is essentially no county level government in Vermont. People like local control. This means that your little town library is not usually part of a larger library system and your little town elementary school is often not part of any larger school system. It's common to have a school district that consists of a single elementary school. (This is changing, though, as the state is strongly encouraging formation of larger districts.) There are about 280 school districts in Vermont, serving a total student population smaller than many single districts in other states.

To my kids, a wooden covered bridge is a pretty ordinary thing. There are two within a mile of our house. They think it's funny that tourists take pictures of them.

Maple sugaring is something pretty much everyone knows about here. Many people either make a little syrup themselves or know someone who does. If you're at any kind of meeting or gathering during sugaring season, people will be talking about whether the sap is running, when they're going to be boiling, etc. You see sap tubing all over and I suppose a lot of people from other places don't know what it is.

The differences in street layout can be surprising and confusing. I grew up in a twisty suburban area in the South and was floored by Chicago's phenomenally well-planned grid system. Then we moved to the Boston area, where the streets are meandering and off-kilter and weird naming conventions like this happen (count the streets named "Hancock").

As an aside: "pop" is wrong and will always be wrong, you're welcome

No carryout alcohol sales on Sunday in Indiana. It's such "common" knowledge that most stores don't even bother to put signs up or otherwise indicate that it's not permitted, leaving out-of-staters to be embarrassed when they get to the checkout line to be told they can't buy the beer/wine/liquor in their cart that day.

Let me give you one better on tornado sirens. The tornado sirens in southern IL are completely different from the tornado sirens in the west St. Louis, MO area. As a Southern Illinois native I was really bemused by the MO sirens. In IL, the siren part is different and there's also an automated announcement that this is a tornado warning. In MO, you just get whooping sirens, no explanation.

One from living in Germany as a kid - public transit is more or less on the honor system. When you buy your (single-ride or daily) ticket, you're supposed to validate it with a little machine either on the platform or in the vehicle. Occasionally you'll see transit police asking people for their tickets and checking the validation stamps. I've seen this described in tourist guidebooks, but have never seen signs on trains, ticket vending machines, or on platforms.

I was traveling to Munich a couple years ago for work, and stopped in to a produce shop to pick up some strawberries for a snack. There were a couple other patrons in there, but no queue and the employees didn't seem in any particular hurry to help out. I picked up a clamshell package of strawberries, walked up to the till, paid, and left. I didn't realize until they started talking to each other as I was leaving the shop that there was in fact a line and I was supposed to wait for an employee to grab the produce for me and bring it to the register.

Many Minnesotan cities have snow emergencies during and after significant snowfall, with each city having very specific rules on where and what side of the street you can park on, depending on which day it is of the snow emergency (this is so snowplows can plow all the way to the curb, unobstructed by cars).

We're not very good at remembering this ourselves, given how many cars are towed during the first big snowfall of the winter. We usually average a couple snow emergencies a month between December and March.

In Memphis, there used to be a very restrictive ordinance against car horn honking. Seriously, it was against the law. So even now, we rarely use the horns in our car, and it's considered very rude to do it. We might give it a little tap if the light turns green and you're on your phone, and if there's a dangerous situation, but that's about it.

Kansas liquor laws are insane. They've changed since I've lived there, but I remember people talking about 3.2 beer, an expression I'd never heard before, which referred to alcohol percentage and where that beer could be sold (grocery store versus liquor store). "Liquor by the drink" was not legal - except in private clubs - so many restaurants had a regular section and a club section. Some counties ("dry" counties) still operate that way.

Not sure if the "blue laws" are still in effect in all of Missouri, but on Sundays, you could only buy food and prescription drugs. Grocery stores would be open, but sections with non-food items would be roped off with signs saying "not to be sold on Sunday". This was in the 1970s and 1980s.

Growing up in North Carolina it was accepted practice that life more or less took a pause for the ACC basketball tournament. We'd even stop instructional time and watch games during class. Asking people what the church they go to and 1) expecting there to be an answer and 2) using that to place the person in a socio-economic class probably isn't particular to the South, but there's place where it wouldn't be a thing at all. North Carolina outside the cities at least used to be a very slow driving place. The five miles an hour over is basically the minimum speed thing I'm used to now, used to be flying down the road in the left lane speed.

Travelling once in New Mexico I got a dire warning from the car rental person that I could become dehydrated in the heat without seeming to sweat because the sweat would evaporate before I noticed it. As a person from the high humidity east coast this never even occurred to me.

In the Denver area we give directions using East, West, South, North, which I think is confusing to visitors or new residents. The mountains are to our West, so we navigate the city with that in mind. Instead of telling someone to take a left on a certain street we say "Go South on Colorado Blvd, then head East on 13th."

When my husband first moved here from Nebraska he asked someone what time it was. She responded with "5 of 3", which completely confounded him. To us it means "2:55."

Great answers everyone! This has kicked up some local (Chicago) things I didn't realize!

Lutoslawski: I-90 also has reversible lanes that flip between "inbound" in the morning and "outbound" in the afternoon.

Which leads to the fact that no one calls it I-90, or any other highway by number. It's always by name, and then on top of that, using nicknames ("the merge", "the junction", "the circle", etc) as points of reference. I assume most places don't require guides to understand traffic reports.

DevilsAdvocate: No alcohol sales before 11am on Sunday in Illinois, but it seems to be posted in most places I've seen. Still, pretty silly. :)

thelonius: LOL - fireflies caught out the Californian visitor too, but I don't think she was concerned about being drugged!

backseatpilot: I got caught out in Toronto with improperly validated (or not validated) tickets on a train. I'm still not sure what I was supposed to do, since I thought I followed the directions, but I definitely didn't do it right. Just a shake of the head from the person checking though!

Grew up in Chicago, talking about expressways. Nowhere else have I found anyone to use the term expressways. Still use the term today, though it confuses some people.

Italians must be baffled by a world filled with people queueing in an orderly fashion. Who am I kidding, they don't give a shit.

Here's the secret gleaned after many years of living here. When there's not a number dispenser (post office, grocery store bread/ deli counters, etc.) the general thing to do is ask in a loud voice "Chi è l'ultima?". Asking who the last person arrived/in line is means theoretically you only have to remember the person in front of you.

Culturally accepted line jumpers are the pregnant and elderly/invalid. Any other line jumpers outside of that category are assholes and you may call them out on it.

Homecoming Mums in Texas gave me a serious WTF when I first learned of them (and I'm from neighboring Oklahoma).

Mums were definitely the big deal on Homecoming, but on all other Fridays during the football season, the cheerleaders also sold football ribbons -- ribbons about 12" long and 3" wide that had the football players' pictures on them, scores of recent games, locations of upcoming games, etc. They were like $1 and served both as a display of school spirit and a fundraiser. The ribbons on homecoming were massive -- probably three feet long and 5" wide -- and had a lot more stuff printed on them. They were meant to be attached to the mums.

I have googled up and down and can't find a picture of anything like the football ribbons I remember.

Another Texas localism: It was standard practice to leave shoes outside after working in the fields or in the garden, etc. But you never, ever put those shoes back on until you first checked to see if something was living in it. There was one summer when a toad took up residence in my dad's mud shoes and had to be evicted every time he wanted to put the shoes on.

Thought of a couple winter-related ones!

Around here in Massachusetts, most towns have blue flashing lights attached to the traffic lights at major intersections. When they're on, it means there's a snow emergency and parking restrictions are in effect. I had never seen those growing up.

Many towns around here will also leave barrels of sand or salt out at major intersections. I'm actually still not entirely sure what the etiquette is surrounding those - are they just for people to use around that intersection if conditions get bad, or can I take a scoop home to use on my sidewalk if I run out of my own supply?

In Tucson, back in early 90's, some of the streets that ran east/west had a middle turn lane that for a couple of hours in the morning were one way only (i.e. not a turn lane any longer). Then, for a few hours in the afternoon, they switched to be one way only in the other direction.

After moving to the mid-south US several years ago, I puzzled over the signs outside Virginia bars proudly proclaiming they had "liquor on and off". Who would advertise that they were frequently out of stock, I wondered. Then I (finally) realized it meant they sold liquor for consumption on the premises - i.e., by the drink - as well as off the premises - i.e., a package store.

Also in southern Virginia, vanity plates with two sets of initials (presumably for the couple that owned the vehicle) are/were very common. Hardly ever see that anywhere else.

Many people not familiar with Florida often confuse "Tampa" with "Tampa Bay," which are not interchangeable terms. Tampa Bay is a body of water. The Tampa Bay area is a collection of cities and towns spanning roughly four counties. Tampa is the city proper. If you say you're "staying in Tampa Bay" when you visit Florida, locals assume you're sleeping in an underwater hotel in the Gulf. ;)

Since a lot of other people have mentioned liquor laws, Pennsylvania may take the cake for most convoluted alcohol-buying system.

-Six-packs of beer come from convenience stores or carry outs that are licensed to sell it.
-Cases of beer come from special
beer distributors, which only sell larger amounts.
-Wine and hard liquor come from state owned stores that are typically closed or have very limited hours on Sundays.
-No wine or liquor in grocery stores, ever. (All those good cheap Trader Joe's wines my friends in other states talk about? Not here.) A small number of grocery stores can sell beer if they have it in a completely separate area from the food, but this is by no means universal.

This confuses the hell out of anyone coming from states with more lax booze laws, but I've been living here for all but a few years since I've been of age and know how to plan a beer run by now.

In Seattle there are entire neighborhoods of intersecting streets on a grid, without any stop signs whatsoever. The locals know that the right of way is determined by who gets there first, not by any signs. If two cars come to an intersection at the same time, the one on the right has the right of way.

Drivers from other parts of the country are often floored when they discover this, because in many places if you come to an intersection and you don't have a stop sign, you can proceed through the intersection confidently knowing that you have the right of way and traffic on the intersecting street will be obligated to stop.

Shopping legislation in Scotland vs England. Scottish people are surprised that supermarkets can't open 24/7 in England; English people are surprised that you can't buy alcohol in any shops (doesn't count for bars) between 10pm and 10am.

Scottish and Northern Irish money often gives outsiders pause, most especially Northern Irish.

Edinburgh's one o clock gun can be a surprise for non-locals who aren't expecting it.

The British version of the American "how are you?" is "ya alright?" or "alright?"

I was used to America, where someone asking "are you all right?" is a serious inquiry. It took me an embarrassingly long time to realize that coworkers, friends, fellow students, etc. were not in fact asking me a serious question about my health--I spent a couple months slightly worried that I looked ill.

If you're in Britain, there is a queue for the bar even if it just looks like a random huddle of people. The process can be fairly intricate, but at a basic level, when you arrive you should note who is there ahead of you, and indicate them to the bar person if they try to serve you first.

Same process can also be the case for bus stop queues in some parts of the country.

In Hong Kong...

- the signs and announcements in subway stations tell everyone to stand still on escalators but EVERYONE stands on the right and walks on the left
- if someone calls you "uncle" or "auntie" it doesn't mean you are being treated as a relative or even with any additional respect at all; it's a translation from Cantonese
- people in shopping districts with suitcases aren't as likely to be travelers as daytripping shoppers from mainland China
- Typhoon Signals, which the government meteorological agency issues during typhoons, run from 1 to 3 to 8 to 10; there is no Typhoon Signal 2, 4, 5, 6, 7 or 9.
- an elaborate hand-signal system to show a taxi driver that you are willing to pay over the meter or that you'd like to cross the harbour is employed by those in the know (wavey swoopy hand motion going vaguely downish = harbour crossing because we only have tunnels, not bridges, between Hong Kong Island and Kowloon!)
- restaurants know that almost no one in the city has space at home to entertain so even local/small/neighborhood restaurants will have a cakeage/corkage fee for diners having a "gathering"
- taking the tram is, most of the time, slower than walking
- no suckling pigs are allowed on the subway - an issue at Chinese New Year given that 90% of journeys in the city are made by public transport!

Blue laws are always good ones.

Colorado's already been mentioned, but we have some pretty great ones.

We recently changed the law so that you can buy liquor on a Sunday now, but you still aren't allowed to sell a car. Because of this, a lot of people go to car lots on Sundays to get an initial look around, knowing they won't be harassed by salespeople.

As to our liquor laws, these are being phased out right now, but nobody is allowed to have more than one license to sell packaged liquor. This means that each grocery store has only one approved store where they can sell beer and wine. 3.2 beer doesn't count as beer, though, so chain grocery stores do sell that. (It used to be legal to drink 3.2 beer at age 18, so we have a long history with watered down beer.) This law has had an upside, too, though. The one license rule opened up the liquor store market for small family businesses. So an immigrant family can come to Colorado, find a good location, and make a decent living running a liquor store. Also, because we don't have places like Walmart and Kroger all selling the same stuff, it opened up the market for small breweries as well. In Colorado, you don't have to make a deal with some huge multinational company to get your product on shelves. Like I said, though, they're phasing this out while trying to protect those markets somewhat, so fingers crossed.

Also, most people outside of Colorado, New Mexico, and parts of Oklahoma and Texas don't know what green chili or even roasted chile peppers are, which freaked me out hard when I discovered that. Every Fall, we have little operations pop up along the roadsides roasting green chiles, and weirdos from other, suboptimal locations don't know what they are.

In Massachusetts, you call a shop where you buy alcoholic beverages a "package store" or a "packie." I don't think anyone anywhere else uses that term.

That second work means something really different (racist term theoretically referring to someone from Pakistan) in the UK. The same type type of shop in the UK is an off-licence (i.e. they have a licence to sell alcohol to be consumed "off the premises", as opposed to a bar or pub) or an "offie". If you said you were off to buy some beer "from the packie" here you would get some extremely strange looks, at best.

This may be a bit obscure for this thread, but I was just talking to some moms in my (Pacific Northwest) baby group about how their families from the southern USA think it's deeply weird that they're still breastfeeding babies that are 4-5 months old. Whereas on the west coast I feel like if you stop before a year lots of people volunteer an excuse for why they stopped "early", usually a medical reason. I'd say this was a generational thing, but my mom breastfed me for over a year, and my friends said it wasn't just their parents but also their cousins and friends who thought they were weird.

In Michigan we have "party stores," where you buy liquor, beer, wine, chips, snacks, milk, etc.- things to eat or drink at a festive event. A 7-11 is a specific brand of party store. This has no overlap in content with "party supply stores" where you get streamers, balloons, themed paper plates, etc. Totally not understandable when I lived in Boston or California.

In the Denver area we give directions using East, West, South, North, which I think is confusing to visitors or new residents. The mountains are to our West, so we navigate the city with that in mind. Instead of telling someone to take a left on a certain street we say "Go South on Colorado Blvd, then head East on 13th."

Also common to Chicago, where the lake is always East.

Oh my god, Party Stores! The bane of my google-mapping existence in northern MI! Because if your Illinoisan ass googles "liquor store" in Indian River your map tells you the nearest one is 154 miles away and that is NOT what you want to hear when you're on the way to a BBQ.

More anti-local knowledge...

Growing up in New Orleans, it was very disconcerting to learn that not many other places believe in "go-cups": Pour your remaining alcoholic beverage in a plastic cup, leave the bar with it and take it to your next destination (usually another bar).

It took a long time to learn about planning ahead in other cities so I could buy my needed alcohol for Sunday on Saturday because New Orleans area stores always sell beer, wine and liquor and it's available at grocery stores not the ABC or package store.

And as children, we could not believe that almost everyone else was at work or school on Mardi Gras day. It seemed ridiculous that we were the only ones watching floats, catching beads and eating fried chicken at 8AM on a random winter Tuesday morning.

Things I didn't know about in Toronto, coming from Glasgow:

Flat fares on buses, rather than saying your destination and paying a variable fare.
Government-owned alcohol stores.
Everybody has to fill out a huge tax return every year, and there are ads for tax software and “tax season” is a thing.
Sales tax not included in prices, so you end up shambling around with kilos of shrapnel in your pocket.
A pedestrian can't cross a four way intersection with lights diagonally.
Cars can turn right on red, in theory, at least.
Everybody knows what direction the roads go in.
You do not talk about the midweek hangover at work, and there's no support-and-cover culture for the mortally hung-over.
Everything is de jure metric, but de facto not.
“Cottaging” is not soliciting for sex in a public toilet.
Advertising is very simple, frequently depicting the product and saying why you should buy it.

Things you wouldn't know about Glasgow:

We don't have a castle, and please stop asking us about it. If we're feeling particularly vexatious, we'll give you misleading directions, and the next person you ask might just play along.
The correct response to meeting (most) drunk people in the street is good-natured encouragement.
Navigation is traditionally done with pubs as waypoints.
Do not be on the subway when a Rangers game gets out.
Don't cross the road in the middle of an Orange walk.
Don't wear football colours to go into a pub you've never been to before.
If someone asks you what football team you support, they're not asking you literally what football team you support, but if you say “Rangers” it means you're Protestant, and “Celtic” means you're Catholic. In the wrong place, the wrong answer could get you hurt.
Weather forecasts are guidelines at best, and it could always rain. Someone without a jacket is a tourist.
Cars don't slow down for pedestrians.
A clear day anything over about 15°C could be considered “taps aff” weather.

In rural Idaho, the government puts up signs telling you to make sure you have "defensible space" around your home.

Two road things that tripped me up when I moved to the west coast.

Seattle: a dashed white line does not always mean "two parallel lanes of traffic moving in the same direction." Unless it's rush hour, on many streets the right lane is legal parking. So you'll be driving merrily along at 35 MPH when, suddenly, a wild parked car appears.

San Diego: The local geography (hills and whatnot) prevent many straight line streets. Where geography gets in the way of the ideal road plan, the segments on either side of the obstruction are given the exact same name. For example, these two addresses on the "same street" are 1/2 mile apart but take 10 minutes to drive between.

mdonley: "In Hong Kong...the signs and announcements in subway stations tell everyone to stand still on escalators but EVERYONE stands on the right and walks on the left""

How to use local transit! I can't even tell you how many cities make this opaque to outsiders. Few or no signs, guides, help, anything. You can buy cards in the station. You have to buy the refillable card at the grocery store/post office/special machine/preorder from the government. It takes cash. It doesn't take cash. It gives change. It doesn't give change. It takes coins. It doesn't take coins. This machine only sells new cards. That machine only gives refills. You tap the card. You swipe the card. You just show the card to the attendant. You have to swipe the card when entering AND leaving the station. No, you don't have to swipe the ticket; you just carry it. Yes, the card is refillable. No, the card is not refillable. You tell the driver where you want to get off. You pull the yellow cord right before the stop you want to get off at. The bus stops at all stops even if nobody is waiting. The bus only stops if you pull the cord. You tell the driver your stop when you get on the bus. The bus or train is a local because the lights are yellow. The bus or train is an express because it ends in an even number. Everyone just knows that train is an express! All the trains on that track are local; all the ones on that track are express. The direction is indicated by north-south-east-west on the vehicle. The direction is indicated by the name of the last stop on the line. You can tell the direction by the side of the road the bus stop is located. There is no direction indicated. Yes, you can get free transfers. No, you can't get free transfers. You pay a flat fare. You pay by time of day. You pay by zone. You pay at the start. You pay at the end. You don't pay. Into infinity....

While we were waiting at a rare red light, I asked our Irish driver if there was "left-on-red" in Ireland. He said, very slowly like I was a complete idiot, "No. Because the light is red." When I explained that we have right-on-red in many US municipalities he was utterly baffled. I guess most US drivers know that it's potentially a thing, even if it's not legal in their area?

Midwesterners in general can usually tell the difference between "summer storm" and possible tornado weather

The siren means be aware of what's going on, not rush to shelter right now.

Much like those signs posted along the highway, it's merely a suggestion.

Which may be another regional rule. In MI, speeding (barring certain areas that you learned to anticipate) and jaywalking are expected.

OH seems to be strict for speed limit endorsement. We tell the international Post-docs that speeding is generally good in MI, but don't do it in OH (maybe they're just strict for MI plates?).

In Montreal if you hear steady honking at night in the winter time it means that impromptu snow removal is underway and they are about to tow all the cars on one side of the street. If you don't leap up and rush out and move your car it will be towed to some random location within a couple of blocks and you will be given a ticket.

The exercise of waking up, throwing a coat over your pajamas and rushing out to move the car can take place up to three or four times a night. But don't worry, you won't be sleeping much anyway as the honking tow trucks get drowned out by the noise of the two lane wide snow blower trucks which are followed by a column of heavy duty massive dump trucks that trundle up to catch the snow from the snow blower nozzle. Each ponderous pass will keep a light sleeper or someone unfamiliar with the system awake for half an hour to forty five minutes, and they may do both sides of the street, plus both sides of another major street that intersects nearby, so you get to listen to the convoy half the night.

I can sleep through this.

Montreal has two children's hospitals. If you are in a bad car accident with your child they may be taken to an entirely different Emergency Department than you are. This is somewhat scary. You have to find out of the kids have been taken to Hopital Ste. Justine or the McGill University Health Centre.

So when I moved to the province of New Brunswick, one of my first questions was, "Where is the children's hospital and how do I get there?" The answer scared the daylights out of me. There is no children's hospital in the entire province. The nearest hospital is the Isaac Walter Killam in Nova Scotia. I had no idea up until then that they would take kids in at a regular hospital, which would have a pediatric department.

In Boston, where I grew up, cars are afraid of drivers, and will stop 15 feet away if you even glance at the curb from the sidewalk. Because everyone jaywalks.

In NYC, cars and drivers are in a detente. If you're in the midst of crossing, and a car is turning on to the road or approaching from a couple blocks away, it is expected to slow. If a car is already coming down your block, you don't jump out in front of it, it won't stop. Everyone jaywalks, but they check to make sure the street's clear first for the most part.

In California, people stand around at crosswalks waiting for walk signals when there isn't a car for miles in any direction. Cars seem to regard humans in the road as they would a bent traffic cone or a pothole --- irritating, but nothing you can't plow over if you give it a little gas.

A couple that come to mind:

In Germany, when you are paying the bill at a restaurant, they will tell you the amount, and then you respond back with the amount you'll pay (on the understanding that the difference in those amounts is a tip). It's also not unusual there for a waiter to come up and tell you their shift is finishing and if you can close off the bill now (if you want to stay, you'll start a new tab with the waiter taking over).

In South Africa, when driving on a road with one lane in each direction, you should pull over as close to the shoulder as is safe (and continue driving) if someone drives up behind you and is going faster, to allow them to overtake you.

Bay Area

Dunno if they still do this, but in parts of San Francisco, it's okay to park in the middle lane on a Sunday. The idea is that it gives churchgoers a place to park. I remember seeing this in the Mission District and a few other places.

The bus that goes to Marin (I think it was Golden Gate Transit?) won't necessarily stop at a stop, even if there are obviously people waiting. You have to sort of wave at the driver.

St. Louis

When you meet someone new, first thing they ask is where you went to highschool. It's how they size you up socioeconomically. It's also how they figure out of you have any friends in common. This happens even if you're not in St. Louis and haven't been there in years. You find out someone's from STL, and it's either the first thing out of their mouth, or if you're like me, you say, "Don't even ask." and then they ask you anyway. This serves as an effective reminder of why you left STL.

NYC

It's totally okay to ask someone what their apartment costs, but (like everywhere in the US) it's never okay to ask how much money they make.

Some native New Yorkers go their entire lives without ever getting a drivers' license. For some, it's a point of pride.

The corner store is called a bodega, and often has a deli counter. All cities have corner stores, but NYC is the only place I've been where the deli counter is so common.

Candlepin bowling has already been mentioned, but I grew up in Maryland and was recently shocked to learn that duckpin bowling does not exist everywhere, and cannot be found here in Denver.

I'd also amend the previous comments about California pedestrian right of way to say that living in the SF East Bay, and especially walking in the neighborhoods around Berkeley, conditioned me to very different right of way expectations. Most cars stop as a pedestrian is even approaching a crosswalk, and stay stopped until you've crossed all the way to the median, if not the other side. It took me a really long time to get used to, and then we moved away and I had to relearn to triple-check that cars really were stopping when I wanted to cross the street.

Like how everyone is a little bit Irish on St. Patrick's Day in most other places, everyone is Polish on Dyngus Day, and everyone knows what it is. (Anderson Cooper was apparently mystified, then hysterical.)

Also Buffalo things -- we would never say we're in "Upstate New York" as the NYC people do. We're in Western New York (WNY). We have expressways, and the numbered ones (and others) are preceded by a definite article: the 90, the 290, the Scajaqueda. Also, downtown (and other) real estate ads will list the nearest Catholic church as a reference point.

In Washington, D. C. and environs, you have to cope with motorcades of various kinds somewhat regularly, including presidential motorcades. The associated road closures cause traffic jams, and for security reasons, you don't get warned about the route in advance or get told which roads to avoid when they are going on.

I will never forget getting a ride home from work from a friend during rush hour (I was working near one of the major routes to Andrews Air Force Base, the home of Air Force One), around the same time as a motorcade. Rush hour is hell anyway when it comes to traffic in this area, let alone when motorcade road closures add an extra complication. We kept trying to take various routes to avoid the motorcade, trying to guess what route it might be taking and avoid it or get around it, but kept running into motorcade related road closures anyway no matter what we tried.

Here's a jpeg explaining what a presidential motorcade may consist of, courtesy of the article I linked above. When you are familiar with them you can usually guess by certain "warning signs" that a motorcade may be coming, and try to avoid it prior to the road closures. This can be a bit mystifying to people new to the area, as you can imagine.

- Paczki, Polish fried dough with prune jam filling, said poonch-key, traditionally eaten only on Fat Tuesday to finish off eggs and butter and sugar before Lent. Available in nigh every grocery and party store and coffee shop in MI around that time of year (sometimes just rebranded jelly donuts with raspberry filling which is delicious and wrong but what ya gonna do), rarely found outside of upper midwest and Polish-heavy towns.

This just came up and apparently not everyone has this...

We have fire horns. Different areas/intersections had a 3 digit code associated with them. When there was a fire you listen to the 3 digit blasts to hear where the fire was if you were a fireman. This originated before the firemen had phones but went on maybe until 2000.

bloot..bloot...bloot.............bloot..............bloot...bloot...bloot...bloot...bloot...bloot...bloot. 317 ??!

Check the code on back the calendar you get from the town hall... "Pearl and Pleasant! Let get our bikes!"
It was always the middle of the night (which to an 11 year old is about 9:30 pm) so super fun to go ride our bikes to the excitement.

I rode past my stop on the Paris Metro because I didn't know you had to lift up on a latch to make the doors open. Also, needing to keep your ticket and put it into a slot to make the barrier open when you want to leave a station. I grew up in Chicago where the CTA trains have automatic doors, and you just waltz out of the station on arrival.

In Chicago, in the 1950's, they tested the air raid sirens (now repurposed as tornado sirens) on the first Tuesday of each month at 10 am. I always figured that the Russians would attack at just that time and everyone would ignore them.

We had visitors from California who kept describing their driving routes as, "We were on the 35East and then took the 494, etc"--every major highway was prefaced with 'the.' Finally my husband, a Californian, told them, "We don't say 'the 494' and it's 35E!" Apparently an LA thing to add 'the' to the freeway numbers. When I lived in Washington, DC I remember people laughing at a radio ad that said, '[business] is just off the Springfield exit of the 495." Clearly made by a CA ad agency.

I find the convention of naming highways instead of using their numbers especially confusing for out-or-towners--the Dan Ryan Expressway or the Kennedy, for example. Also confusing-- long routes having different names in different jurisdictions--Route 50, Lee Highway, Leesburg Pike, for example.

The tornado siren is common here; 1:05 on the first Wednesday. When we first moved to this St Paul suburb in Dakota Co, not only did the siren shriek, we got a female voice telling us what to do--take shelter now, this is a test, whatever. Quite weird and had a sort of 'throw down your plows, take up your arms; the revolution has arrived" vibe, particularly if they went off in the middle of the night. They don't talk anymore; now it's siren only.

Minnesota also has no car shopping or liquor buying on Sunday. Local jurisdictions also can have municipal liquor stores run by the town or whatever. This means the variety & number of liquor stores varies by town. So, in a town with municipal liquor, chances are there will be no Trader Joe's or World Market type stores because the city or town has a monopoly. In non-municipal liquor towns, there is no liquor sold in grocery stores either (in spite of endless bills/debate in the Legislature), so grocery stores who sell liquor have separate entrances to the liquor sections & often 2 transactions are required. And second the snow parking regulations--every city is different and woe betide if you don't know night plow routes from day plow from downtown. St Paul's regs.

In San Francisco the only people (pedestrians) who cross against the lights are tourists. Here in Portland the tourists are usually the ones waiting patiently for white-guy-says-walk while locals cross randomly, often without looking.

The law in Oregon says that once a pedestrian steps off the curb, they immediately have the right to cross even if it's not a marked crosswalk. This is great when you're a pedestrian but terrifying when you're a driver. Everyone here jaywalks, often without looking for cars.

At a sort of "meta"-level I think this speaks to how particular and idiosyncratic this sort of thing can be: it was about 16 years ago that I moved away from Minnesota to Montana, but still the moment someone starts talking about 35E and 494 I get pangs of nostalgia about going into "The Cities" to visit a museum or an arboretum or the Twins for a ballgame.

It's particularly weird when I'm back there visiting family during the summer and the tornado sirens go off during their monthly tests, as described above as something that's normal over there (but unheard of over in Montana). Half my brain is familiar and feels nostalgia, the other half is unaware and panics for a moment. Like I'm trapped between worlds and don't know how to process two realities.

This is in Mo Nickels' list of transit variations, but I was confused as hell when I rode a Pittsburgh bus route where you put your cash in the farebox as you get off the bus. This didn't apply to all routes in the system, just certain outbound commuter routes.

Also, you CANNOT eat on the Metro. My information is a few years out of date, but there was definitely a time when this rule was really enforced. Apparently other places it's no big thing?

Again with the heat -- heat exhaustion at Memorial Day parades is a serious concern. Groups whose performance is at all strenuous often have specially designated members walking around pouring water down people's backs. And even so, at my suburb's parade you would see performers peel off, lie down on someone's lawn, and hyperventilate.

Newark, NJ and Newark, Delaware, are not that far from each other geographically, as distance in the U.S. goes with fast travel and communication, but are still pronounced differently. The Delaware one is "nu-ark", and definitely two syllables, and the New Jersey one is "new-irk", but the two syllables are not distinct and it can sound more like "nerk" when said quickly by North Jersey folks.

Freeways in SoCal are "The 10," "The 5," "The 101," etc. and never "I-10," "I-5," etc. The exception is California State Route 1, which runs all along the coast. Locally it's known as Pacific Coast Highway but referred to as "PCH."

Dunno if they still do this, but in parts of San Francisco, it's okay to park in the middle lane on a Sunday. The idea is that it gives churchgoers a place to park. I remember seeing this in the Mission District and a few other places.

It's technically illegal but only variably enforced, and never near many of the longstanding Catholic congregations. This is basically vestigial evidence of the power the Catholic church wields in San Francisco even still. (Semi cite.)

From places I've lived...

In Tasmania, which unlike the rest of Australia is very hilly, if you get stuck behind a log truck on a winding rural road and the driver puts on his right indicator, it means it's safe to pass. As we drive on the left and the strict meaning of a right indicator is that the truck is about to turn right, this relies on your knowing that there's no actual road coming up on the right that he could conceivably turn onto.

In Canberra, you'll encounter more roundabouts in a day than in a whole lifetime spent elsewhere in Australia. The Federal Parliament is, appropriately, surrounded by a giant roundabout.

In Australia, you park on the side of the road in the same direction as the traffic. In Britain, you can park on either side of the road in either direction.

In New Zealand, almost all jams, spreads, peanut butter etc. are sold in plastic jars.

New Zealand Vegemite tastes subtly different to Australian Vegemite.

(Different English-speaking countries have different conventions around using "different to" and "different from", to the point where I can no longer tell which is used where.)

In Scotland, people say "outwith" for some (Australian) senses of "outside" (e.g. something can be "outwith your experience", but you wouldn't go out the door to "go outwith").

In Britain, Australian "pants" are "trousers". In Australia, British "pants" are "undies".

British people stopped saying "gotten" a couple of centuries ago. Americans and Australians didn't. If you're an Australian in Britain, it's okay once you've got used to it.

In Edinburgh, locals rarely carry umbrellas. The rain isn't usually heavy enough to justify it, and if it is then the wind will turn it inside out in seconds anyway.

If you drive over a recently resealed road in Australia and a car comes the other way, you should hold your hand against the windscreen to absorb the shock if the other car throws a blue-metal stone into it, so that you only end up with a stone-chip instead of a crack in the glass. In Britain, newly-resealed roads don't ever seem to have the same loose surface gravel on them, so nobody does this.

In Edinburgh, if you ask for vinegar on your chips (as in "fish and") it means you're from Glasgow or England. In Australia, it also means you're from Glasgow or England. Edinburghers have brown sauce on chips. Australians have tomato sauce on chips.

In Britain, your national insurance contributions will go on hold, affecting the level of your eventual state pension, if you are out of work for an extended period and don't claim National Insurance credits. In Australia, your pension entitlements aren't tied to what taxes or national insurance you've paid during your lifetime, only to your income, assets and length of residency at the time you reach pension age.

This is a fun thread to read through.

An addendum to the Montreal snow removal system is that the parking signs are crazy and often take a few months to get used to.

There are a lot of words commonly used in English that come from French, my favourite being the "Dep", short for "Depanneur" which is a corner/convenience store. But you can also buy beer and a small selection of wine there. But only until 11pm. I miss them.

Downtown I always felt it safer to jaywalk than to cross at a light, at least you were paying attention.

Where I live now in the BC interior, you can't leave your garbage outside, even in a bin, or else you attract bears. Seriously, don't do this. There's a reason that every park has bear-proof garbage cans. Also not super common knowledge but it should be: Black bears are not really dangerous unless you startle them or piss them off somehow, but you still need to be cautious. Cougars are really what you should be scared of if you're out in the wilderness or on the edge of town, especially if you're small and by yourself. And avoid Grizzlies if you can.

In Wisconsin, it's common knowledge that as long as you're their parent or legal guardian, children and teenagers can legally drink with you anytime, anywhere. Even if the kid is in elementary school and you took them to a cocktail bar.

There may be other places where it's legal, but I've never been anywhere that normalizes underage drinking quite like we do here. Alcohol consumption at all stages of life is foundational to our cultural identity. Some of my very earliest memories involve sipping kiddie cocktails at up-north dives.

Also, you can't park overnight on any street in the entire city of Milwaukee without a parking permit. If you don't have a permit, you can call in your license plate to the police department so they won't ticket you, but you can only do it three times a year. There are absolutely no signs posted about this anywhere, you just have to Know.

In Massachusetts, you call a shop where you buy alcoholic beverages a "package store" or a "packie." I don't think anyone anywhere else uses that term.

Not true! Rhode Island is also home to the Package Store. Rhode Island is also home to coffee milk, which is not a kind of coffee; it is milk blended with coffee syrup.

Americans misunderstand the Canadian (and British) "sorry". They think we're apologizing for something, which is understandable. But it's only a verbal tick. We don't actually feel regret or remorse when we blurt out "sorry" in a random situation.

In Ireland, "sorry" means "move, please." My cousin's Australian husband lived here for two years responding "that's OK" before he got straightened out. He still gets teased about that.

Tourists in this country are routinely blown away by the fact that we pay for parking by text here. (There is also an app for this, of course.) The slightly older "pay and display" model of paying for parking used to really confuse my parents, who of course still pay for parking in their town with quarters in a meter.

Ah, this brings back a memory. I grew up in a smallish but rapidly growing Northern CA town. The first time the ice cream truck stopped on our block, I was 5. My mother was on the phone when I ran to her to ask for a dollar. She hadn't seen an ice cream truck since her youth on the East Coast (where they were "Good Humor trucks"), so she flat out told me I was pulling her leg. Luckily for me, the ice cream man turned his jingle on a moment later... Suddenly she was more excited than I was and got off the phone in quite a hurry. We shared a twin orange creamsicle.

The weather in the San Francisco Bay Area (and generally along the California coast) is pretty unique. Here are a few things that can surprise outsiders:

* As you travel a few miles in a straight line, you can be in the fog, then under clear skies, then in the fog again.
* Summer temperatures usually vary by 25 degrees, and can vary by as much as 40 degrees, from the coast to the valleys.
* Near the coast, early summer is the foggiest time of year, and early fall (well into October) is the hottest time.
* It can get cold quickly when the sun sets. Locals usually pack layers for a day out.
* Rain is feast or famine. Some winters, we get a week or more of unrelenting storms. This rainfall doesn't pour like a Midwestern thunderstorm, but it steadily adds up and one such week can provide a third of our rain for the year.

The town where I grew up doesn't get much wind (this isn't a very authoritative source, but I'm not really sure where to look for average wind speed), and I genuinely didn't understand what windbreakers were for until I went to college in Minnesota--I thought a fleece would be fine as long as it wasn't raining.

Also weather-related: my first Minnesota winter was brutal, and when the snow finally melted I was disheartened to see all the mud and dead grass. That feeling paled in comparison to the next spring, when I realized that mud season happens every year.

(other things that were new: the feeling of the inside of my nose freezing in the cold; serious thunderstorms; fireflies, which I had never thought about much but always kind of imagined to be a myth. I took for granted wild blackberries (the most delicious invasive species) and recyclable can and bottle deposits.)

In SoCal the "Three Day Rule" is, you don't go in the ocean for three days after a rain because of bacteria and pollution runoff, but a new study shows it may actually be a 10-day rule in some areas. Also, if you're visiting the beach, those are not "creeks" those are storm drains and you want to plant your towel far away from them. And if the air smells like poop and you see surfers and kite surfers fleeing the water you should get out, too, because something nasty just came out of those storm drains.

Church bells commonly chime the quarter hour in England. You know which quarter hour from the length of the chime (a quarter, half, three quarters or the whole of the Westminster chimes?), and the number of times the bell then tolls on the hour tells you which hour of the day it is.

Centuries-old buildings are commonplace in the UK. Churches, castles, private homes... even my secondary school dated back to the 17th century. (There are plenty of new buildings too, obviously, but it's easy to take for granted that *of course* the village church is Norman or there are Roman bricks in the remains of the town wall.)

In the Netherlands, there's a siren that goes off at noon on the first Monday of the month. I lived there four years and never found out why.

In Japan, summer has a sound effect: the screaming of cicadas in the trees.

Japanese railway platforms have markings to show you where the doors will open, and which is the first-class carriage. Station name signs by the tracks show the direction of travel and the name of the next stop as well as the current one. On-board announcements tell you which side the doors will open, and a jingle plays on the platform before they close. Japanese tourists and expats must find trains elsewhere in the world perversely and bewilderingly unhelpful.

German friends were shocked that the default for bottled water in the UK was still, not sparkling.

In the UK, when they ask you at a cafe or sandwich shop "eat in or take away?", it's not just so they know whether to give you a bag or a plate: they're legally obliged to add on sales tax if you're eating in, so it costs you 20% more.

Oh yeah, and every year we celebrate the anniversary of the thwarting of a plot to blow up the Houses of Parliament by letting off fireworks and burning a guy, or rather a Guy, in effigy. Good clean fun for all the family. Fireworks are very much a cold-weather thing in the UK - 5th of November and, latterly, New Year's Eve.

For the people debating and discussing what US military bases play in the mornings and afternoons -- it seems to vary a little by location and quite a bit by service. The Air Force Bases I've been on have played Reveille in the morning, with Retreat in the afternoon. The afternoon Retreat was followed immediately by the National Anthem.

The Navy base I work on now plays Reville in the morning at 8AM, immediately followed by the National Anthem. All cars are supposed to pull to the side of the road, all people are supposed to stop, come to attention, face a flag (if one is near), and be respectful. Civilians should hold their hands over their hearts. Military of course remove their covers. In the afternoon at 4PM, Retreat is played, followed by the National Anthem (again). Same procedure as the morning.

Of course this is entirely my own observation and your mileage probably will vary.

Chatting with some foreign colleagues this week, it dawned on me that the general home buying process as we do them in the US or at least in my state is not universal to the Earth! My colleagues told me that in Finland, they would not hire a licensed inspector and make demands/negotiate repairs before a sale; on the other hand, the buyers might come after them years later if a problem were to develop, whereas here it would be really hard to make demands after a sale is complete....

In much of US cannabis culture, a spliff containing tobacco is a rarely-invoked specialty option rather than the default. Blunts rolled with cigar wrappers are a distinct class of consumption mechanism.

All of the places I have been in Europe, a standard joint is laced with tobacco (or, not infrequently, it is more that a hand-rolled tobacco cigarette is laced with bud or hash). Local stoners cling fervently to a broad range of folk beliefs about the use of tobacco in this context: It helps the herb burn more evenly, it makes the smoke less harsh, the temperature is optimal for THC uptake, it will mask the smell, etc. Openly questioning the tobacco provokes howls of disbelief; rolling a j without any is well-nigh unthinkable.

Fostoria, OH is the only place I've ever seen a drive-through convenience store. Everything you'd expect at your local Circle K, Speedway, or Pilot, but you don't get out of your vehicle.

Remington, VA is the only place I've ever experienced regular drunk driver checkpoints. Friday nights, the cops were out with their roadblock. 600 people in residence, but they wanted to be sure they caught the drunks.

Athens, KY is pronounced AY-thens. Buena Vista, VA is pronounced BYOO-nah VIH-stah. Butt Hollow Rd. in Salem, VA is not pronounced as one might expect, but closer to buh-TALL-er.

After working in a convenience store in Tucson, AZ, where beer and liquor were both sold 6 a.m. til 2 a.m., moving to VA with its ABC store confused the hell out of me.

In Maine, at least when I was a teenager, it was completely normal to use Canadian change interchangeably with American. There wasn't a lot of it, certainly nothing like a 50/50 mix, but you might easily have a couple of quarters or pennies in your wallet.
When I went to college in Massachusetts, I had a mutually frustrating conversation with the cashier at a convenience store where I tried to convince her that this weird elk quarter was just fine and she insisted that that was money from a different country, and not, in fact, valid in the US.

Not being able to pump your own gas in Oregon has been mentioned before, but I just wanted to reiterate how weird it was when I moved out of state. I traveled a lot within Oregon but not outside of it when I was growing up, so it was just the way things were everywhere we went. I didn't learn to pump my own gas until I was 22. And now, when I take my Texan husband back home, I always have to tell him, "okay, roll down the window and say 'fill it with regular'" -- because that's how you say it!

Back in the day, locals used to give directions to the Swan's Island Ferry as follows. "Follow the Road. Make the right at Reed's Store, go down to the water towers, and hang a left until you get to the ferry."

The water towers were dismantled in 1980. Reeds store burnt down in like 1987. Those exact directions were still in use when I left town in 1994. Legitimately, there weren't that many roads and if a tourist couldn't find the water on an island - while not surprising... well...

I once was infuriated when I booked a hotel room to visit Missouri. When I said a sincere "Thanks for all your help," and instead of "you're welcome" or "my pleasure," I got back "Uh huh" (kind of drawn out and slow and with an undertone like a teenager's 'What-EVER').

I found this so extraordinarily rude that I raged about this to anyone who would listen, and seriously contemplated calling the person's manager. Then when I actually got to Missouri, the WHOLE TOWN said "Uh huh" instead of "you're welcome."

In North Carolina, bars can serve liquor by the drink only if their food sales exceed 30 percent of total receipts. Otherwise it has to be a "Private Club." So pure bars around here require you to buy a one-time membership (usually less than $10) or get a member to sign you in before you can drink there. Which can be perplexing for out-of-towners, wondering why they have to have a member sign them in to your standard issue shitty dive bar.

I grew up in Asheville, NC. Actual locals pronounce it as if it rhymes with "Bashful." (This is fairly common throughout the Appalachian/Blue Ridge region.

Wooster, Ohio, is pronounced like Worcester, Massachusetts, and is home to the College of Wooster, not Wooster College. This has led Wooster students to embrace the cow as a secondary mascot, and the college bookstore to sell shirts which read "Wooster is not in Massachusetts" on the front and "Thank God" on the back. You also learn to differentiate different Amish sects based on their buggy styles and signage.

In other collegiate matters, the core of the University of Virginia is known as the Academical Village, the entirety of the University's property is known as Grounds (not campus), and it is a faux pas to refer to undergraduate students as "freshman", "juniors" and the like.

Another New Jersey thing; knowing "what exit" you're from, and being able to use that as a guideline to determine where in the state someone else is from.

Pedant: I grew up in NJ, about 20 minutes from the nearest Interstate, so "what exit" was pretty dependent on which direction you were coming from, and which highways you took to get there. I don't actually remember any of the numbers. (Coming from the south, I usually get off of the Turnpike at New Brunswick, which I think is #10 or 11?)

Other Jersey-isms that I didn't think about until I left the state:

Everybody knew that the state was weird about pumping gas, so that one almost doesn't even belong on this list.
Deer in the suburbs. The spectre of Lyme Disease was pervasive while I was growing up, to an extent that I've never seen replicated elsewhere
Availability of good pizza.
Availability of good diners. Diners as community gathering places, and generally serving the role that bars, Starbucks, Waffle House, and fast-food joints serve elsewhere
Proximity to good beaches. After moving to DC, I dated a guy from Michigan who had never been to a beach.
Transit, but only commuter trains.
Jug handles exist. U-Turns at red lights are never allowed.
State politics are very idiosyncratic, and don't follow national trends.
A very large percentage of High School seniors leave the state to go to college, and don't return

In Pennsylvania and New Jersey, every town has at least two places called Brothers' Pizza (or Brothers Pizza or Brother's Pizza). I'd always assumed this was the case everywhere in the US, but I guess it's mainly a "large Italian population" thing.

Saying "quarter of three" to mean 2:45 is a thing that I heard a lot growing up near Philadelphia too. My wife is from Michigan so I've had to start saying things like "ten to" and it takes a conscious effort.

In Japan, there's actually a weekly show on prime time that is more or less exclusively about stuff that's unique to one place but that locals think is universal.

When I grew up in Fresno AKA Fresberg, in the middle of California's Central Valley AKA The Valley, we used to have Tule fog ("two-lee") in the winter. I remember walking to school under a bowl of fog with maybe 20 yards of visibility. They used to close schools out in the country because the fog was too thick for the school buses to run.

Driving in the fog was a scary experience, especially on the freeway: you had to drive slow enough to be kind-of safe but were always worried about getting hit from behind some idiot driving full-speed. Every few years there would be another 50-car pileup on the 99 freeway that goes through the Valley.

I've been going back to the valley every month or so for the past twenty years but haven't seen any fog for at least the past ten. I think it's a combination of warming temperatures and farmers pumping all the water out of the ground. I miss it. Under the fog everything was quiet and you could hear water drip-dripping from the ash trees.

I grew up in Phoenix. Every summer we'd have monsoon season - it's the rainiest time of the year. We've had lots of flooding this week because of it, actually (I had to wade home two blocks in knee deep water the other night...) And even if it didn't rain, there was still a good chance of getting haboobs. A lot of people from outside the state have no idea what I'm talking about when I mention monsoons and haboobs.

I didn't realize until a few years ago that not everyone knows what javelinas are. My cousin moved to AZ from back east- anywhere east of the Rockies is back east- and was pretty shocked the first time he saw one. Same with Gila monsters. To us Arizonans they're just one of the myriad of desert animals we learn about in school and on field trips to the Phoenix Zoo or Sonoran Desert Museum, but I've met a lot of people as an adult who have no idea that venomous lizards exist in the United States.

Now that I live in Northern Arizona, I've learned some more local quirks. One of my favorite foods is Navajo tacos. I haven't met too many people from outside the Four Corners region who know what they are. Another popular local term is rez dogs- the majority of the dogs in animal shelters around the Navajo and Hopi reservations here are strays picked up on the rez. I've confused quite a few people by telling them my dog is a rez dog, with them assuming I'm just shortening the word "rescue".

When I moved to Peoria I was bemused to discover that hummus is srs bizns and everyone has ultra specific preferences and will go to special stores and even the supermarkets make it fresh in the deli from local recipes (because the area had a huge wave of Lebanese immigrants after the Civil War and remains very Lebanese). People have die-hard allegiances to any one of several Lebanese markets or restaurants for their hummus and they fight about it at parties. Sometimes you have a potluck and seven different hummus partisans bring their preferred hummus (and leave you the leftovers). Now when I go to other places I'm always disappointed in the hummus because it's just mass-produced and nothing to have fisticuffs over, and I forget that taking hummus so seriously is a local quirk.

I've had my husband in the Midwest for twelve years and I still haven't taught him what tornado weather looks and feels like, nor does he have any idea how to find tornado shelters when out and about.

Living in the north, how do you dress for cold weather... and how do you drive on snow or ice?

More specifically: you can't pump your own gas in New Jersey. (Full service only, by law.)

Travelling outside of Chile, there aren't necessarily mountains always, and even if they're there, they're not necessarily to the East, so how in hell do you orient yourself?

Not sure if the "blue laws" are still in effect in all of Missouri, but on Sundays, you could only buy food and prescription drugs. Grocery stores would be open, but sections with non-food items would be roped off with signs saying "not to be sold on Sunday". This was in the 1970s and 1980s.

Just to reassure everyone: You can definitely buy liquor on Sundays in Missouri, since like 1975, apparently. Although I feel like I remember seeing some stores that still wouldn't sell liquor on Sundays as a kid in the '80s. But yeah, no worries now.

In Houston, on Sunday you can't buy hard liquor at all or beer and wine before noon (or as I called it, afterchurch.) I worked at Whole Foods and there would be a huge rush before the store closed on Saturday so everyone would have beer for Sunday football.

Oh, no one's mentioned the garbage truck music in Taiwan yet? You don't have to be from Taiwan to develop a reaction to it; a week's visit is more than enough, once you realize the persistent mobile music is not from an unusually large number of ice cream trucks.

The 5pm song, in many places in Japan. People just ignore it without comment. In fact once I waited for it to be over, then asked "what was that?"

"What was what?" So normal it didn't even register.

It's actually pretty clever, it's a daily test of the emergency speakers, but substituting the tune Yuyaku Koyake for the annoying sirens.

In San Francisco, there are sections where BART and MUNI both operate as subways, and both use the same stations, but have different and non interchangeable tickets and entrances in said stations. This is incredibly confusing for tourists.

Also In a lot of other places with subways, the subway runs until after the bars close. That is not true in SF, where the subway stops running around midnight.

ctmf, the sirens are, to my understanding, at least nominally intended to serve as signals to farmers that it's time to get up/take a lunch break/quit for the day, at least in more rural farming communities. The songs also vary by municipality — where I worked for four years, the noon chime was "Love is Blue"

Where I grew up in New Jersey, the Fire Company blew the siren at noon. Don't know if they still do. I rather suspect that it was an attempt to make a necessity (testing the siren) into a virtue.

I grew up in the South and have lived in a lot of other places and had to adjust to a lot of local quirks (currently missing SF Bay Area transit customs and figuring out how to keep the Colorado sun from killing my skin and hair). But living in Salt Lake City for a couple years in the late 90s was definitely the steepest learning curve so far:

-Fry sauce, y'all. This has since spread to surrounding states, but not too far out to the rest of the country.
-I was super confused when, my first week working at an outbound telemarketing company, they shut the phones down on Monday nights to avoid disturbing people participating in Family Home Evening.
-I'm still not convinced that my friends who grew up there weren't pulling my leg when they told me it's traditional for school students to ask each other to dances via elaborate pranks.

In Houston the frontage/service roads alongside freeways are called "feeder" roads. (Or just "feeders.") Being from L.A. I'd never heard any of the terms because our freeways are elevated.

(Also there are crazy U-turn lanes there.)

A few more Massachusetts things:
128 (not Route 128, just One Twent- Eight) runs around Boston. It is concurrent with I-95 for most of the trip and the signs these days almost exclusively say "I-95". Everyone still refers to it as 128.
The Southeast Expressway is a chunk of I-93 to the southeast of Boston. If it's backed up to the gas tank, you're in trouble.
They actually have rotaries. (What everyone else calls roundabouts.) Learning to drive in one is a crucial skill. I remember being surprised that I didn't see rotaries anywhere else in the country when I was growing up.

Back to the great pop vs soda debate: In Virginia, where I'm from, and some other parts of the south, we say neither. It's Coke until more information is required.

Me: "Hey, I'm going to the vending machine. You want a Coke?"
You: "Sure, hey thanks!"
Me: "What do you want?"
You: "I'll have a Sprite."
Me: "Coming right up!"

Mom: "Stevie, I put some Cokes in the fridge for you and your friends."
Stevie: "Hey guys, who wants what? We've got Sprite, Dr Pepper, and Mountain Dew. Motherlode!"

Code-switching in conversation (using multiple languages in the same sentence or convo fluidly) comes super naturally to me and folks in my culture/country of origin (South & South-East Asia), but it freaks out my monolingual Western friends. My (White Aussie) matey bugged out when he watched a snippet of some Indian dance music competition where the judges talk in both Hindi and English - he was all "how the hell do they do that?!" and I'm thinking "uh, it's natural?".

Squatting for toilets seem to be a thing that escapes White people for some reason. Squatting can't be THAT hard, geez.

Urban deer. I live in small town in BC and we have deer everywhere. They have learned to wait for cars to cross the road and even seem to favour crosswalks. They hang out in town and have no fear of humans. Tourists often go crazy when they see them, we don't give them a second look unless they are trying to get into our gardens.

I am surprised nobody has mentioned the definite article in freeway names. If you're from Los Angeles or now all of California, you probably call it the 101, the 5, the 210, the 405, etc. People elsewhere do not do this and will think you're weird if you don't call it just 101 or 5, like it's a name and not a thing.

In my defense, is there another 210 freeway? No? Then it's THE 210.

Also, "for here" vs. "to stay." West Coast, "for here or to go?" East Coast, "To go or to stay?"

I was talking to a couple from Toronto about the hilarious way Californians use the definite article for highways and got blank looks. Apparently it's a thing there too?

Also, "for here or to go" is what we say in the Mid-Atlantic region of the East Coast.

Yup, the definite article is used for highways in Ontario - at least the "400-series" highways. The 401. The 400. The 416. The 417. For non-400-series highways I would say "Highway 7" or "Highway 69" rather than "The 7"or "The 69".

Rumble strips on rural roads in Iowa. One of the things that makes RAGBRAI not only possible but popular are the well-built and (usually) well-maintained rural road network in Iowa, and they have two to three patches of rumble strips on roads leading up to stop signs. RAGBRAI riders have a particular gesture for indicating their location (palm down, shaking or wiggling fingers) to warn riders behind them that they're about to get a very bumpy ride if they don't avoid the patch. I've never seen them on roads (and I'm talking about the lane itself, not the shoulder) in Illinois.

Fries in the Netherlands ("patat") are most commonly eaten with a generous helping of "frietsaus", a slightly more vinegar-y variation of mayonnaise. Just ketchup as a topping is unusual, unless it's in "special" sauce, which is ketchup, the aforementioned frietsaus, and chopped onion. A variation of that is to replace the ketchup with peanut sauce (satay), which is called "war" sauce.

Regarding bells and sirens in Japan, at least here in Chiba, there's a chirping sound every morning to mark 7:00 am. The first time I heard it, I had a job where I set my alarm for 7:30, but every morning, I'd here this chirping, and for months I wondered what the hell it was. I though it must have been some extremely punctual obnoxious bird. Nope. It's a little "hey there, it's 7:00 am" reminder. I quite like the five o'clock chime. Not a fan of the 7:00 am bird call.

no right turn on red in nyc busts people every time.

that law was created specifically to bilk innocent New Jerseyans and I for one will not stand for it

what I mean is, New Jersey has right-on-red, and in drivers' ed class they specifically warned us that New York did not.

also a fun New Jersey fact: people not from here seem to think that the state is a filthy garbage state full of pollution and strip malls. The reason for this belief is partly that it's true but mostly that

the transit corridor for the whole Northeast region goes through New Jersey
so there's a huge amount of people going through New Jersey on their way to somewhere else
the specific highways involved (95 and 78) were built through NJ's factory and urban areas
there is a specific spot on that highway that smells like dirty socks
it just does
most people will know to roll up their windows at that point
but do you know what kind of people travel from New York to DC on a regular basis? people who work in either government or media
reporters, talk show hosts, congresspeople, lobbyists
they all think that New Jersey smells like dirty socks

In fact, there are several national/state parks and land reserves in New Jersey, including the Pine Barrens which is big enough to drive across it for two hours without any cell reception. And we have some beautiful scenic parking lots.

In a small town, a friendly stranger who comes up and starts talking you, or even makes eye contact or says hello, is normal, and ignoring that person will mark you as potentially dangerous or crazy.

On the highway from Denver up into the mountains, there are wide spots designated for putting chains on your tires. I don't know how widespread this is in the western mountains.

In the Netherlands, breakfast is cereal or bread. Sometimes eggs, as an addition.
Lunch is bread. The question 'what's for lunch?' is never heard, because we know what's for lunch. Bread is what's for lunch. There are many, many tasty things to put on the bread. Sometimes there's soup as an addition to the bread.

Cake is never a dessert; it's a special treat, reserved for birthdays or other notable occasions. If someone offers you cookies, you take one and say thank you. Cookies are never eaten by the plate. You get one cookie with each cup of coffee or tea or glass of lemonade.

Squirrels are red, never black or grey.

Bicycles are mainly used for transportation, not sports. Bike helmets are only worn if you are a child or doing sporty things in a sporty way, in which case you will also be wearing specific sporty clothing; in all other cases, normal clothing is worn while riding a bicycle. People seen riding their bicycles in business attire are commuting and this is unremarkable. Many people own a city bike and a mountain or race bike.

On your birthday, you throw a party. You make sure there are snacks, cake and drinks and invite your friends over, because it's your birthday. They will generally bring a gift. Throwing parties for others is generally not expected.
On birthday parties, people sit in a big circle, eat cake and complain about the weather and parking tickets. In some regions, you are expected to congratulate all of the present family of the host(ess) as well.

A few things I realized when I moved from the US to the UK:

• In DC and Los Angeles (and possibly other American cities) it is common to drop words like "Street" or "Road". Instead of "La Cienega Boulevard," you'd just say "La Cienega." I did this when I first moved to London and it took me a little while to realize you can't do that in an ancient city whose street names evolved over centuries. When there's Park Lane, Park Road, Park Mews, and Park Street, it's not terribly useful to just say "Park."

• When I first started watching Olympics coverage on the BBC, I was baffled that I never heard the official Olympic theme. I finally discovered that it is not the official Olympic theme, but simply a piece of music that American networks treat as if it were. Few people outside the US have even heard that piece, and nobody associates it with the Olympics.

• It turns out that expecting your politicians to assure you that your country is the greatest one on earth is a uniquely American thing. (Or, at least, it's not a European thing.) Similarly, British politicians are not expected to wear little flags on their lapels at all times, and it now seems a little weird to me that American politicians are.

That's because the overwhelming national attribute of the United States, above wealth, above freedom, above democracy, is insecurity.

Here in rural Georgia, people talk about highway numbers, and once in a while names, as if everyone absolutely knows what they are. 341! 95! 82! 17! The spur! I never got used to that and I still forget what they are all the time.
