Hi Rich,
Looks like Marc answered the majority of your questions. As he said, the field is still open to anyone with an NHRA or IHRA legal stock/superstock car. We don't close a field until at least one pair has completed first round. You can find all our rules in our Bylaws on our website:
http://asra-ne.com/bylaws.htm
Our membership dues are $350 and you can join at any time but are only eligible for points and the ASRA portion of the payout after dues have been paid. Non-members are only eligible for the track portion of the payout. For example, if a race had 40 cars, the winner would get $400 if a non-member but would get an additional $600 if a member and another $400 on top of that if a member with the Banks Chevrolet sticker on the car (total of $1400 to win).
The racer entry at the track gate is $60 I believe (sorry, I was just there and can't even remember the exact number. Hopefully someone else will correct me). Two time shots with qualifying based on reaction time and then eliminations completed all in the same day. We do run heads up for same classed cars and randomly check all cars for weight.
Hope to see you there and feel free to ask additional questions.
