I echo Scott's comments:
1. It was a GREAT school last year (I was there crewing for a buddy). 30 cars max I think, good student/instructor ratio, and other than an SRF that kept spinning, everyone stayed pretty level headed.
2. Do have crew if you can. You are on track a lot and won't have time to work on the car. Crew is not required, and I made it through Savannah school (in a British car no less) without crew, but it's asking for trouble if you don't carry someone down with you.
3. I may be instructing this year, but if not (and even if I am), come see me if you need some help. I'll be in a big green Suburban with yellow and gold stripes -- RTP Racing on the side. Can't miss it, especially in a "light" paddock.
Good luck, and hope to see you down there.
