When I worked in Cambridge the past two years, I would ride the 28 miles to the end of the Minuteman Trail (actually used to go a bit into Bedford too) almost every day. Even though it was a little bumpy and chopped up by town roads, it was a great ride, and your pics brought back a lot of fond memories. I recognize all of them occasionally long for the crisp autumn and early winter air (but not the winds!). As consolation I have the 32 mile round trip Hawthorne Trail in Gainesville, FL. And I can ride it year round.....
