I've got a few buddies who go to Azusa or GMR regularly. I've been there myself one time with my friends. But I've never pushed my car, even when they kept saying "why don't you go faster?"
I told them, I've got a family, I've got a career, and I'm not going to put my life and yours as risk like that.
I've got one buddy who specifically bought a Scion FR-S just to go these California un-sanctioned road courses (GMR, Asusa, Angeles) and it's pretty reckless. Thank god he doesn't have a girlfriend.
