I ran pretty actively with Philly region in 2 Honda Civic 1500S's, a CRX Si and most recently a Sentra SE-R. I've been away from it now for probably 4 years. I want to get back into it with the BMW. It doesn't seem like Del Val Chapter has many (any?) autocrosses, although the driving school schedule looks pretty good.
I agree that the time committment at Philly Region SCCA is daunting- they now do a run I, skip II, work III format which puts you there all day. That's tough when your wife and kid are waiting for you at home!
What chapter is NCC?
