I remember pulling up to the gas island at Eller's Grocery in Chesterfield county, VA with my briggs powered minibike back in the late '60's. Had to go inside and get the attendant to come out and pump 5 cents worth of gas! When I graduated to a Yamaha mini enduro, then Honda SL125, I would always wait until I had to switch the fuel petcock to reserve before filling up. If I fueled before going on reserve, I could not get it to take a full quarters worth. I can't remember what the price per gallon was, but it must have been in the mid 20's.
