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.
The Smithsonian Air and Space museum is a little ways outside of town away from most of the Smithsonian museums but it's super cool because they have all these actual historical air and space craft just sitting there and you can walk right up to them.
+1 for this!! They have the USS Enterprise space shuttle and the Enola Gay among others!
