Castle Air Force Base is closed, isn't it? I stopped by the air museum quite a few years ago when the base was still active, intending to do a short walk-around. Ended up spending 4-5 hours checking out all the cool stuff. They have just about everything you'd expect in military aircraft there. The SR-71 was there at that time, but the windows and undercarriage openings (wheel wells, etc) were covered up to prevent inside views. Anyway, that's a really impressive place and glad to see its still open.
