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. Residents are encouraged to inform these groups of maintenance issues observed on trails (downed trees, trails becoming overgrown, etc.) by emailing TCMCchair@hopkintonma.gov or hopkinton.trails.club@gmail.com. For more information, visit hopkintontrailsclub.com. The next monthly trail volunteer day is Oct. 1. Participants will meet at the Emerald Hill soccer field parking lot on Greenwood Road and work on the Greenwood Trail. Depending upon the size of the crew, there might be some work done on the Betty Fitzpatrick Trail as well. Volunteers should bring gloves, shovels, hoes and rock bars.
