The Hopkinton Trails Club will host a walk on the Braim Farm trail on Saturday, Dec. 9, at 10 a.m. Attendees should park and meet at Penny Meadow Lane and South Mill Road. The trail is a pretty, somewhat hidden area with a lot to see. Some areas are wet, so walkers should accessorize appropriately. For more information, visit hopkintontrailsclub.com.
