Why do the motorcycle cops leading up a motorcade wave (both hands) when they go around a corner? What are they signaling? [more inside]
I've lived in Washington DC for 5 years, so you'd think I know what good stuff there is to do. And I guess I've done a lot of it, but now I want to take my girlfriend out on a fun date that isn't the monuments, the (national) mall, a movie, or 'just dinner.' Any good suggestions for Saturday evening? There has got to be a boatload of fun non-tourist stuff to do here!
