I've been here, http://www.antiqueairfield.com/apm/
Lots of history and cutaway views. Very interesting, free will donation.
That's where the National Antique Airplane fly in is held. Members only, though. Hagan came one time and they wouldn't let him in.

All he had to do is give me a call, and he could have been my guest.. but.. most cell phones don't work there.
