If there are no takers for Saturday and people would prefer to put something together for Sunday, I can do a local club-ride on Saturday.
On that note, there is an unscheduled NSC ride out of Topsfield if anyone is interested. It usually pulls a decent crowd, especially if the temps are going to be as warm as predicted. There are usually enough to run separate A,B and C level groups. Nice marked ride with 25 35 and 50 mile routes:
