I wanted to point out a good resource for those attending the school, particularly as first-timers. The Tire Rack Solo Novice Handbook has some very good information about what to expect at an autocross event.
There are still many spots available for the school, but I'll guarantee that it'll fill up before the deadline (it did last year), and once the pre-reg spots are gone, only day-of-event registration is left (and it's almost 50% more than pre-registering).
