The Hopkinton Trails Committee and the Hopkinton Trails Club have created a monthly trail volunteer day on the first Saturday of each month from 9 a.m.-noon. The next workday is June 6 and will focus on clearing brush along the Cattle Run Trail. Participants will meet at the Hughes Farm parking area (192 Hayden Rowe Street).
