The nation's first fillin' station specifically for gas turned 100 over the weekend. Happy birthday to the Gulf Refining Filling Station in Pittsburgh PA. Prior to that, gas was usually sold from barrels at various roadside establishments. According to the National Association of Convenience Stores, the station also gave away free maps. They also say---and this surprised me because I remember paying even less when I was a teenager---that the average gallon of gas sold for 27 cents back then. Now, if you factor in inflation adjustments, that would be the equivalent of $6.39 per gallon today. Does that make you feel any better about the price you pay at the pump? Nah, me neither. DB
