Until the Yom Kippur War in the fall of 1973 and the subsequent oil embargoes, there were three stations lined up next to each other on the north bound Central Expressway (US 75) service road between Spring Valley and Belt Line Road in Richardson TX that were always trying to knock each other out. The standard low price of the three was 21.9¢. At times they would get down to 19.9¢ or even to 18.9¢ once that I recall. During that period I had at various times a Fiat 1100D, a VW Type III Squareback (both great vehicles for the drive in, wink wink, nudge, nudge, say no more) and an early 3 main MGB (better than I had originally thought at the drive in, but not as roomy as the others, especially that Fiat). I was in the hand the guy two bucks and say fill it or stop it at $2, whichever comes first crowd. Most of the time I got change back.
After that it hung in there ranging from 50¢ to 60¢ a gallon and I remember everybody carrying on about how if gas got to a buck a gallon they'd just have to quit driving. If all those folks were going to quit driving, why is there so much more traffic now?
