When I went to school in Georgia tech, Atlanta, the Office of International Education organised a trip to Washington. We went to all the monuments( and there are a lot of them), even to the White house(unfortunately no pics!). But the best part of the trip for me was climbing to the top of the Washington memorial early morning. I spend fifteen minutes atop the memorial watching the capital city come alive. If you are in DC I would recommend doing this. If you not in DC well no worries, here are pictures from my trip (way back in 2008).
