I've never had a garden before. I recently bought a house in Canberra with a small established garden, mainly native Australian plants. It has a drip watering system. There isn't a lot of room, but there are a few things I have always wanted to grow, and I've got no idea whether it is possible to fit them in somehow, or where I should put them. I know I can't do anything until just before spring, but I want to start planning now. [more inside]

What do you do with a screw that turns freely and won't unscrew?

Help me find the right pair of minimalist shoes! I've been a member of a Crossfit gym for six months, which means I've been exposed to the peer pressure regarding Vibram FiveFingers. Plus, I'm starting to travel a lot (and lightly) and want a pair of running shoes that have a small footprint (heh) when packed in a suitcase. Recommendations for this recreational runner? Are Vibrams a good option? Which model? How do I size them? I'm training for next October's Portland Marathon, if that makes a difference. Bonus points for shoes available at REI (though that's not a requirement).
The SRS light on my 2003 Honda Civic comes on when the ignition is turned on and remains on while the car is being driven. I googled this and understand that Hondas as well as other cars have this problem. I can take it to a mechanic to have it diagnosed and repaired. Or I can turn it off myself which I'm tempted to do since it appears that Honda has a faulty system that has nothing to do with the airbag --just the light. But there is a small part of me that wonders and is concerned if something could be wrong with the airbag. Does anyone have experience with this?
