I live 2 hours away from the NMUSAF by car.
I have been a member for years.
Anyone with even a fleeting interest in military aviation should see it at least once in their life.
Also on certain Fridays you can sign up to tour their restoration shop. Well worth it. Of course right now their big focus is on the restoration of the Memphis Belle. It's amazing to see her in pieces all over the shop.
