does anyone use 100LL av gas ?

In 1975 I was partnered in a drag car that had 13:1 comp.
We put some 130 octane avgas in the car, really perked it up.
There was a small airport on the way to the track, we'd just back up to the fence and they'd fill er up, no problem. In the fall that year the guy at the airport said that there would be no more 130 avgas in the near future, only 100LL, he was right.
