Going to DC with a friend for a couple days and am wondering if Hexbear has some ideas on what to do. We already have a list of the 4 (maybe 5) museums we're going to, so probably don't need any suggestions there. (Though feel free if somewhere was super cool to you.) Preferably things close to metro and/or downtown.
Last time I was in DC I did a Segway tourwhich gets a good coverage a history of the place.
Also the Kennedy Performing Arts Center. Of course the museums. Smithsonian and Air and Space Museum.
FDR memorial.
