The National Geographic should be on everyone's list of places to go in DC! I go every time I'm in town. There is always a free exhibit in the windows surrounding the outside of the building and can be accessed 24 hours a day. There are usually 2 exhibits inside accessible with 1 ticket and a 3D movie which must be purchased separately. The exhibits are always top notch! I saw Day to Night a photo exhibit. IT. WAS. AWESOME! There is also usually a free exhibit in the lobby of the National Geographic working building next door.
