Gorgeous sunny day in mid-70s. Absolutely lovely ride thru neighborhoods, paths & rail-trails (ARRT, BFRT & MCRT). Parts were familiar, others not. No tough hills, either! Tom's report: Our fifth ride last week was an exploration of various bike paths, including the newly completed section of the Bruce Freeman trail extending south to Sudbury, and of a portion of the Mass Central trail to the west of the Sudbury crossing. At the trail intersection we met with an enthusiast who was anxious to share her local knowledge about the trails and history. The trail intersection is the remnant of a rail crossing called the "Sudbury Diamond." Check out this Wikipedia entry: https://en.wikipedia.org/wiki/South_Sudbury_station When not on the trails, we were mostly on quiet roads in various neighborhoods, which made for pleasant riding.
