The Plan: https://ridewithgps.com/routes/27044624 Chilly Day - planned to extend a Ken Ride to a metric. Curt leader, Barbara Martin, Bernie, Clyde K, Dr Frank Hubbard, Eliz Wicks, Jack Donohue, Marc Baskin, Maria Noya, Rich T, It wasn't a super hilly route, but I could not keep pace with anyone and would run out of time and light for my metric. I bailed at the Acton Fire Station and returned to the start for 21 miles. From there the plan was 21 miles out on the rail trail to Cambridge and 21 back. Turns out the rail trail distance from Concord is about 17+ miles so I had to make up some when back in Concord. Interesting apparel adjustment - only 2 thin fabric layers at the crotch and a lot of wind got thru - so took out my rain had cover that is light, water tight fabic and used it for a jock strap - more info than anyone needed - but for future reference.
