This is the unofficial, unverified, incorrect, subject-to-change, prelimnary, unrevised, and just plain wrong schedule for next year:
April 24: PIR (or ORP)
May 1: PR
May 15: MRP
June 5: PIR
June 26: MRP
July 9: SRP (double race weekend)
July 24: ORP
August 31: PR
August 14: PIR
August 21: MRP
September 25: PR (or PIR)
October 9: ORP
As Steve pointed out, there's lots of uncertainty, double-bookings, incorrect information, and confusion. The schedule isn't settled yet, but I'm posting it because I know it's good to have even a sketch of an inkling of an idea, and trust that others will understand that it's probably incorrect and subject to change even if it did correctly reflect the current state of planning.
