I didn't see any wrenches spinning, but I did see a couple of team members standing within a 12 inch proximity of the bike. There was one person with a WERA Official shirt with them, so I assumed it was only validation and not modification, but they were there for an awfully long time. So, looked like a duck, quacked like a duck, it was most likely a duck.
I dont think you will ever make money down there or have good turnout.unless you go to northen california where most racers are i dont see it happening. do it at Thunderhill when afm is not racing and you will have full grid. even if AFM was not on same weekend as fontana I dont believe many would go there.
