Well over 10 years ago, I was invited by a rail vehicle manufacturer to an industry event that they were holding to promote one of their vehicles. It was held at the TTCI test facility outside Pueblo in Colorado. Pueblo also has an aviation museum so it was inconceivable that I would go all that way and not check it out while I was there.
Most of the exhibits are outside in some pretty harsh sun so they are rather sun-bleached. There is an interesting mix of old types on display while a few are indoors and look in better condition. Helicopters and vintage fighters are always going to be good for me so hopefully there is something in here you like.
