Thanks for the kind words Mondo
Tom, in case you might be wondering our TD rules are here:
http://bostonmoto.com/pdf/track-day-rules.pdf
We allow passing anywhere in the Advanced group, and stress that passes must be made safely with appropriate room between bikes. The job of our Control Riders that are circulating and the professional corner working staff (we do not use volunteer corner workers like some other orgs) is to keep an eye out to ensure passes are made safely in all groups.
Recently we've had the pleasure of a few top LRRS guys (Fred Stearns, Christian Cronin) who have attended our track days and the feedback was very positive. Fred may actually be in a similar situation as you are, he's getting a bit tired of the stresses of racing and not enjoying it as much anymore, and says he has a blast at our events.
Maybe that helps, maybe not, but you clearly have options!! Feel free to PM us with any specific questions you may have.
