I took the ART basic class with Team Promotion, then went back for a general track day the following year with the same group. Both events were at Summit Point. Overall, a pretty decent group of people who know that the key to having a successful day is having fun while being safe. They have skilled instructors who took time to monitor and address every student's riding and critiqued accordingly.
My only gripe was they wouldn't let me use my tank-mounted video camera. Apparently they feel if you need to video your runs you must be planning on showing off and doing something stupid. I disagree, and told them so, but no dice. Rules are rules, they said.
