Hee, hee! Last spring I was driving past Edwards Air Force Base and decided I wanted to visit the flight test museum. As I drove up to the gate I saw a lot of motion up ahead. There's nothing quite like the feeling of an M16 pointed in your direction! Needless to say things have changed since 9/11. The only way to visit the flight test museum now is if you have military id...kind of a shame since I'm a big airplane nut. I've been to the Air and Space Museum and the Air Force Museum in Dayton twice, and would have loved to add that one to my "been there" list.
I’ve been to all of those. Another one you may want to add to your list is the Strategic Air Command museum just outside of Omaha.
