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

I remember my Dad pulling in to a gas station in our 68 Charger RT and if it took $3 to fill it was sucking fumes!!!

In 1979 the year before I started driving gas was around .50 a gallon , by the time I was driving in 1980 it was a dollar. Anyone else remember gas rationing where you could only buy gas on odd or even days depending on your license plate number??? MAN I'M OLD!!!
