Walk on the new section of the Assabet River Rail Trail, from Stow, MA to South Acton, MA (6.8 miles round-trip).  We will meet at the organizer's home and carpool a short distance to the trail.  If you would like the option of a shorter walk, that can be arranged.  We may have lunch at one of the restaurants in Maynard afterwards.  Bring water, sunscreen, insect repellent and hat.
