Eric,
After 20 years of master's racing, I have come to understand that there are all kinds of reasons why more "mature" racers call time on their seasons and I'm sure you have yours. However, as we talked about last weekend, I would urge you to reconsider early hibernation.
A quick look at the MAC results shows you in 8th place with only one race to go. Assuming everyone around you in standings shows up for Cross at the Kiln, you are likely to forfeit position if you don't go. Would be a shame to give up an entire season's work in that way. Most importantly, it will cost you front row spot for next years Nittany Cross openers (both days), on a course notorious for first lap pile ups, as 100 plus racers, jacked up to start their season well, charge off the line.
Thing about a series, which I'm sure isn't news to you, is that points at end of season count just as much as those in the beginning. Everyone is tired and it's hard to commit to another month of training since final race isn't until 12/14 but if you do it you won't have a winter of second guessing yourself and the warm glow of a front row start next year to keep you warm till spring.
