Rt. 2 West, 4 miles beyond Rt. 495, take exit 38B for Rt. 110 East/111 North. Go 2 miles to rotary and follow Rt. 111 North/2A West toward Ayer. In 0.7 miles, turn left onto School St., just before the courthouse building. (If you get to the bridge over the railroad tracks, you've gone too far.) Follow School St. 1/4 mile to Pirone Park.
Modified version of the former West Podunk route on back roads in and around Shirley, MA, voted America's Most Historic Small Town by ePodunk.com (really!). Short ride includes Groton, Sterling, Lancaster, Bolton, and Harvard. Long ride adds nice loop in Townsend and Lunenberg. Both routes now have lunch stop at Kimball's Farm in Lancaster and avoid busy retail area in Leominster. Limited food and drink opportunities, so BYO.
NOTE NEW STARTING LOCATION THIS YEAR ONLY, DUE TO CONSTRUCTION AT RAIL TRAIL PARKING LOT. BE SURE TO USE THIS YEAR'S VERSION OF GPS AND/OR CUE SHEET (LINKED BELOW).
