Our nation's capital

Hey regular readers and new visitors, I don't have any new musical goodies today (I promise to put up something new by the end of the coming week), but instead wanted to send out a request. I'm in D.C. until Wednesday for work and don't have much of anything to do outside of normal work hours. I'm heading over to Som Records in a few minutes, but am looking for other suggestions of things to do (outside of the obvious visitor stuff like the monuments and the Smithsonian museums). Digging advice is always much appreciated, but I'm also interested in any other happenings (is anyone worth checking out playing records in the next few days?) as well as good places to grab food and lesser known places to check out as a visitor. You can either hit me up in the comments or shoot me an e-mail at trunk.of.funk@gmail.com. Thanks in advance, GA.
