Some of the more "DE" event operators (HOD, SV, TMR) can still accommodate people with real track cars. I imagine all the amateurs in various vintages of Cup cars end up in the club racnig (POC, PRC) or NASA? The real challenge around here is making sound if you're at a DE and not part of a race event.
