We have a local series here that is NORBA sanctioned. We have to follow the NORBA rules as far as moving up. I am not sure if these rules apply to the series that you are participating in. It may be worth checking in to for future reference. In your case, even if the races are sanctioned you would not be forced to move up because the classes are so small.

That being said,if I were a fellow racer, I would not consider you a sandbagger if you did not move up becuase you did not do the entire series, and because you sound like a relatively new racer.

I am not sure where you are located, but make no mistake, the girls that race around here are very competitive, and take the sandbagging issue VERY seriously.

Sounds like you are having fun and kicking butt! CARRY ON!!!!!!!!!!!
