Depends on your experience level. Some groups are not set up to help begineers or never-evers. I am an instructor for Northern California Racing club..and Hooked on Driving. I also teach for BMW Club and Audi Club. I use to be a NASA instructor.
I think Hooked on Driving is run well. Audi club is doing a Sears Point event on Oct 9-10th..that I will be instructing at. I might hit the BMW club event at Sears as well..not sure yet. Check out Motorsportreg.com for a listing of local events.
Hope this helps.
