The Hopkinton Trail Coordination and Management Committee (TCMC) and the Hopkinton Trails Club have created a monthly trail volunteer day on the first Saturday of each month from 9 a.m.-noon. On Jan. 6, volunteers will meet at the Ice House Pond parking area and work to fix a dislodged trail bridge at Berry Acres. Participants who have hip waders should bring them, along with shovels and cordless drills with T25 bits. If there’s time, volunteers also will work to fix erosion issues at Center Trail.
