Yes they consider placing an ad in the Club newsletter marketing. Unfortunately they don't get it.
Our local NASA chapter is very organized and well run. Ryan F. is the National Chairman and this is his region. I think he would like to hear about your region to see if he can get them organized. They typically have 200-300 HPDE and race entries for every event, usually more race than HPDE.
They also have an Enduro series that usually runs at night so it does not interfere with the regular schedule.
SCCA could learn alot from NASA in So-Cal.
The SCCA Nor Cal Region is also very organized and has large turnouts. This has become one of the problems for them. It takes two days just to have a single regional. I normally run two classes in Nor Cal just to get enough track time to justify the trip.
Oh well at least I have lots of choices.
