All the groups will let you run. Pretty much your choice. I wouldn't worry too much about tech inspection if you have run on the tracks before, you know what to do to make it right. If not, call me.
If you are safety conscious, I would recommend the arm restraints, a neck support and the best helmet you can afford. PAS is very pro safety and has the best support team in this area. Larry is very proud of his team and would be glad to tell you all the specifics. Good guy too.

Next event is the St John's GP on Sept 4 weekend. Last year, this was a blast. A cobra track for sure; they take over the airport with lots of straights.
If you want PIR, you must run with the other groups as PAS does not go here. NASA is having an event there in early Sept. Check them out at

Asra guys are cool too. I haven't checked there site for a while. Too busy and it's been too hot.

I run the RA-1's and like them a lot. Guess I'll see you out there.
