I forgot most of the things I learned, but I do know that the State Capitol needs to fix the dome every now and then, and that builders built Darth Vader's head on the outside wall of the Washington National Cathedral. The Washington Monument also has a part of it a different color than the rest, since construction stopped for a while for a war (or something else.)
It was pretty cold and windy on the first day I got there, but the weather gradually got warmer day after day. It'll most likely be hot in the summer. The buildings and parks all look really neato. There are a bunch of monuments and museums to see, but I don't think the people there are polite and all. I've seen people walk by a homeless man playing makeshift drums (just a bunch of empty barrels), record a video, and not even donate a single penny. I'd only go to Washington D.C. for a vacation/tour, but I wouldn't live there personally.
