I would recommend a visit to the Pima Air & Space Museum in Tucson, Arizona as they also offer exclusive bus tours of the 309th Aerospace Maintenance and Regeneration Group (AMARG), also known as the "Boneyard." The facility is located adjacent to the Museum at Davis-Monthan Air Force Base.
The museum and optional boneyard tour make for a unique day looking at air and space history. World's Largest Airplane Graveyard Hi Res Photo
