First I was old enough to become very aware of gasoline was somewhere in the 20-25 cent a gallon range, about 1965. There used to be "gas price wars" at the Newport, WA / Oldtown ID border
Me too, I can remember Dad pullin' up to the pump at the FULL service station, get the oil checked, wash the winder and top off the tank in his 56 Chevy for 5 bucks.
