Dubstep Shep

So my roommate recently got me out to the local porshe clubs autocross weekend at the sheriffs training course in Midwest City. They don't mind other cars or non members there as long as you pay to play.

Question is are there any good groups/places to race around OKC? I know Hallet is always a good place, but I was hoping to see some other mustang guys so I can hang around them and maybe pick up some helpful info.

Thanks!
