For those of you thinking when to show up, DVOA is also hosting no less than two events on Saturday with short-ish courses - White, Yellow, Orange, Green @ Perkiomen (website needs updating on that), and White, Yellow, Orange @ Star Village. At just under an hour's drive apart, you could take in both, as a warmup for Sunday's event.
