I like to think that I was a very small part of the reason Mopars were popular at Minot AFB. I was in sales at Main Motors in Minot in 1964 and our dealership bent over backward to give good and fair deals to GIs. Our sales manager said the best salesmen were happy customers, and the base was a constant source of new customers. I personally sold two of the new '64 Barracudas to airmen.
When the auto hobby shop had a new car show, we were given the best spot to display our cars when we brought them out the day before the show. The Chevy dealer was arrogant and not very popular on base, so during the night the TSGT running the show loosened a muffler on one of the Chevy muscle cars. When we picked up the cars that evening, the Chevy made it about a block before the muffler blew off and had to drive back to town sounding like an old clunker. The Air Force guys laughed like crazy. :cheers:
FWIW, thirty below was mild for ND! When I was a dumb kid. I went hunting one year when it was 52 below!
