Thanks for the ping. I paid $1.67 a gallon today at the Waterford (M-59/Crescent Lake Rd) Mobil.
(I remember it at 19 cents a gallon sometime back in ‘66/’67 in Lincoln Park MI)
You must be fairly young then. I can recall gas selling for 33 cents a gallon in the 1960s. But taking into account the massive inflation from then until now, the 46 cents (even though only a short-term gimmick) is much lower than the price back then.
