does anyone use 100LL av gas ?

Several of us racers back in the 90s used to run it. Never had any problems, can not buy it now since the County took over the smaller air ports around Vegas. Couple of my nhra stocker friends still use it in the stockers went they bracket race, one guy get it out in Overton, he has an aircraft tail number from a friend that allows him to buy it...the AV gas runs just as fast as the expensive racing gas they use a the nhra national events...
