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

When I got my first car running in 1966, I was working at an Humble station pumping gas, checking under the hood, washing windshields & checking tire pressure. Gas back the ranged from .18 to .25, depending upon the gas wars. The were 4 stations on the corner, Humble. Sinclair, Gulf & Texaco. Over 4 summers, I worked at all of them at least once.
