Went there about 2 years ago, turned up about 5 minutes before they closed, I forgot about mountain time, anyway a guy came out to the car park and said that they had just closed, no problem say’s I, I am staying up at Las Cruses in NM so can pop back tomorrow. As I have found with a lot of US private collections once they know your a Brit, the doors open, within a few minutes the lights were back on and the guy had me sitting in the Mustang that was being returned to flight, could not do enough for me, was very reluctant to take a donation as well, can recommend a visit to anyone who is near there, great collection and great people who run it.
