Well look what's sitting in the desert just outside Tucson, Arizona.
The 309th Aerospace Maintenance and Regeneration Group (or AMARG) is a massive facility adjoining the Davis-Monthan Air Force Base with over 4,400 aircraft stored across its 2,600 acres. Just look at these images from Google Earth of the vast fields of planes. Even if you're not an aeronautics enthusiast, you can't deny the patterns created by rows and rows of aircraft are striking and beautiful in their own way.
To get inside you'll have to sign up for a guided bus tour with the Pima Air & Space Museum. Expect massive lines of B-52s, F-4 Phantoms, and A-10 Warthogs, plus helicopters, commercial airliners and more. You'll also head down AMARG's "Celebrity Row" of retired aircraft, which includes the the F-100 Super Sabre, the first U.S. Air Force aircraft to break the sound barrier. Save time to explore the hangars exhibiting hundreds of aircraft back at the museum, too, including the Space Gallery and the Arizona Aviation Hall of Fame. Tickets for the tour run $7/adult and do sell out early, so reserve your seat ahead of time.
