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 7, and it will be to clear a western connection from the Colella property to the Hughes Farm Trail. Participants will meet at 192 Hayden Rowe Street.
