Washington, D.C. definately. It's so beautiful, like, and artest painted his masterpiece on a canvas of earth. (is that corny or what??) oh, and someone said that it was to post modern and a facimalie of Paris, which I totally disagree with. First of all, it's greek revival, not post modern, and second of all, it looks nothing like paris. When you walk through D.C., you can tell it was planned. It looks...new. Paris looks old. they are different! lol. The best part of D.C. are the parks, the monuments, the architecture, and the free museums. If you ever go, make sure to check out the botanical gardens. they are AMAZING.
