Many years ago? I can remember gas for 19.9 in Siloam Springs, AR. Probably 1967.
Sounds about right. I saw it for about 19 cents in Oklahoma around 1969.
In the spring of 2009, during the crash, I saw it for $1.24.9 where I was living - that’s the lowest I’ve seen since not long after 9/11 when I filled up my old Jag sedan for about 85 cents a gallon.
