I had to go do some repair work on some scenery back in 1993–to a mall in Enid, Oklahoma.
The Indian (oops, Native American) who drove me talked about oil, when I noticed so many inactive oil rigs.
“There is much oil under us”, he told me.
I did not understand then, but I certainly do now. I wish I had shots of those shut-down rigs, 19 years ago now, because if Oklahoma had oil then, it still has it now, as it did way back when.
