Uh huh. Wise guy, eh? :nerd
We get people signing up for A when they want C every once in a while when the C group is sold out. Not a good idea. If we don't have room, we don't have room. Those rider's only option is to ride in A or sit out. We're USUALLY able to get people into the correct groups but sometimes it's not 'till after lunch. Do yourself a favor: just sign up for the group you regularly ride in and you'll be a happy camper.
