We arrived a half hour before closing time, but the gentleman manning the museum that day was very gracious and even allowed us a few minutes extra. He gave us a brief tour of the Deke Slayton exhibits, lots of antidotes on Deke and some of the unusual bikes and artifacts, including an official moon rock. We really enjoyed the bike collection and had fun looking for the bikes we owned as kids. There is also a scale where, if you are brave enough or thin enough you can step on to see how much you weigh on earth, the moon and one other planet I can't recall. The moon weight rocks! Fun museum, nominal fee.
