I've been twice; once with my wife, and once with my ( at the time) college-aged son--left the wife at the campground.
For aviation lovers, it is a must see!
Among all the great aircraft, I think the one that impressed me the most was one of the cargo planes--You could play a game of basketball in there--and there was a row of seats way up high by the windows, but no floor under them. Also the trapeeze fighter that was supposed to engage fighters while the bomber stayed on target. Then the fighter was to catch up with the bomber and hook on to the trapeeze. Right! I think they were most likely considered expendable in a real combat situation.

Another thing that impressed me was the reduction in size of nuclear bombs as the technology improved, and the yield increased.
