Autocross Tracks
 

Any good tracks in the Bay Area? Or like... enclosed places where I could practice? :p Maybe a school or two? Dang, I don't know what I'm getting myself into.

laguna seca!

Yeah, I'm sure I can afford to rent that one out. ;)

You wont find a empty place you can go "practice", your best bet is to hit as many events in your area as you can.

i find that churches have nice parking lots to practice driving in...
of course not from experience but just saying
no ones usually there like 10 pm on a weekday and pretty spacious.

mormon churches are great. usually pretty big.
or so i've heard
