If you live in DC, there's so much to do that it's hard to figure out what to do first. How much have you checked off of the unoffical DC bucket list?

Only go out at night like a vampire until September. I'm down with that. Just make sure you're one of those bad-ass vampires and not a glittery Twilight one or we're gonna have some problems.
How much have I done on there? Most of it without knowing about the list. It wasn't hard, considering most of it involves siteseeing/museums/food.
