One of the nice things about being somewhere that isn't home is the sampling of new, local, things. In the case of when I visit my friends near DC this means one thing and one thing alone. Beer.
America had a reputation for really bad beer and if you drink the likes of Budwiser: 1) it's true (cue the canoe joke); 2) there are many many other beers you could be drinking which are really very good.
