We'll be parking in a parking lot right on Groton Street. There's additional parking around the area where there are businesses closed. We'll start on the Ayer, end of the trail and ride to the other end in Nashua, NH, then back to our cars. We usually stop at an ice cream stand in Pepperell on the way back, so you may want to bring a little money with you. The round trip is just over 25 miles, altogether, on a mostly flat surface.
