there will be about 40-50 instructors on that day. Grp 1 will have instructors riding shotgun. Each group will see about 50 cars on track. dress casually as it is really hot on the track and bring a lot of water for drinking. Wear shoes and have helmet on hand. other than that just have loads of fun and make new friends.
