The AutoX event at Fontana sounds intriguing, but I don't think I want to wear out my tires and brakes too much. I'm sure it would be a fun thing to try, though.Also, Speed Ventures is a well run organizer of track days. Here's their schedule:
11/6-8 Streets of Willow
11/7-8 Willow Balcony
11/20-22 Fontana Speedway - ROVAL
11/21-22 Fontana Speedway - Autocross
12/4-6 Streets of Willow
I'm planning on going for the Fontana Speedway Roval on 11/21, but am still deciding about going.
