How much did a gallon of gas cost when you first started driving?

26 9/10. My dad ran an Enco gas station back in the 60s and as a kid I remember one of my (many) tasks was changing the sign's numbers from 27 9/10 to 26 9/10 on the weekends. Years later, I asked my dad why we'd lower it a penny every weekend and he told me the other gas station (Shell) across the street needed corporate approval to lower their prices and their corporate office was closed on the weekend.
