I used to be very involved in the organization of the events of all of the clubs around here. I just don't have the time these days, but I do try to help out whenever I can.
All of the clubs are basically screaming for help, They always have been. If one club seems more organized than another it is just because of a little better organization from one or two motivated individuals. If you want to help out in any area (including making sure that nobody gets unfair advantages in any area) then tell someone and they will gladly accept your help.
Let me assure you that ALL of the clubs in the area will let you get in some pratice time on Saturday if you come help set up. The one place this is not going to be the case is where they only have the site for one day and do all of the setup on Sunday morning.
I will say that over the past there were usually open invitations made at drivers meetings and club meetings that if you help set up you can have some pratice time. We definately used to alter the course set up from Saturday, or run it backwards or something of this nature.
In addition, if you stay around after the event and clean up TSCC usually picks up the bill at the pizza place afterwards for those that helped out.
I guess I do agree that the incentives should probably not be a competitive advantage. Probably if someone mentions this at some of the meetings, TSCC will change the policy and go back to praticing on a different course, or running it backwards or something. I think it should be approached that way and you will see a change.
