You are correct Bill Van that the owner of "Long Gone" was Les Brown. I seem to recall that this series was inspired by the IROC series of car races in which racers from different auto sports competed in identical cars. I believe they came from F-!, Nascar, SCCA, USAC and maybe some other organizations. I think it was 12 drivers.

I think that Powerboat covered what was going on, and I'll bet Bill Muncey wrote some stuff too and maybe Mel Zikes.
