I just called the CCS office and spoke to Kevin, he disagrees and feels that only a handful of guys run the whole series regardless of the distance of events.
If the Atlantic region consisted of four weekends at NJMP and four weekends at Summit, with a double-header thrown in; I'm pretty sure I would be able to race all of those events (assuming they spaced them apart enough).
VIR, CMP and Loudon are just too far to go. The last time I raced at Loudon (I live just about in between Loudon and VIR) I got home at around 5:00 am. It involves two vacation days, since I have to leave Friday morning to not be wiped out on race day and after Sunday races and another eight hours home, I can't see straight Monday morning.
I think the thing that Kevin doesn't realize is that as racers, the older we get, the more we can afford to participate in the sport. That said, the older we get the harder it is to drive all night after racing. I'd love to go Loudon or VIR again. For me, there are safety (falling asleep behind the wheel), cost and time issues with traveling that far.
