The Udvar-Hazy Air and Space Annex

The Udvar-Hazy annex is out near Dulles airport. It's a huge hanger with 200+ planes from the Smithsonian collection. They have the Enola Gay, a Black Bird, P51, P40, Concord, Stratoliner, F16, and more... The only thing that missing is a B-17 and they have plans for it. Its a really good stop if your out near Dulles.
