Alas, Northern Nipmuck and Merrimack unavoidably collide this year. Fortunately, this shouldn't happen again for quite a while - Northern Nipmuck will hover around the Saturday of Easter weekend with exceptions for when that falls before early April, and Merrimack has become pegged as the second Saturday of April. The next likely collision is in 2020 (keep your fingers crossed!).
Pete Dubendris has decided to let the Diamond Hill race take its place in history, and put his available time into his Wrentham Forest Challenge race. That race isn't part of our series, previously because of scheduling. Perhaps it could be added now, but with about 25 races already, we risk permanently disabling our Stoneheads.
