Please join the Metropolitan Area Planning Council and its partners for a bike ride on the Mass Central Rail Trail from Waltham to Sudbury, a distance of roughly 10 miles. The ride is part of a summer series of rides exploring some of the Boston region's most exciting greenways, with a focus on locations where key gaps in the corridors must be closed. The ride will last about 3 hours, including stops and discussion along the way, and ending with a drink at a local establishment. For more information and to register please visit the MAPC event page and contact the event leader.
