John I am afraid I'm going to give myself away as a really old guy. When I was at NDSU the expensive station on the south side of campus (not there now) had gas at 24 pennies a gallon.
Ghost, I must be a couple years older than you. I remember filling my pickup in the midst of a gas war for $.19 a gallon at a station on University Drive. I think the name of the station was Bjornsons or something like that. They were known for being the most aggressive pricer during the wars in the early seventies. Haven't ever seen any competition like that in Bis-Man.
