I decided to stay close to home and save driving time, but I also got flat terrain. Drove to Rte 117 parking lot. Did Mt Misery for starters. Then a typical route to Walden Pond. Then headed to the new area around Lincoln's water reservoir called Flint's or Sandy Pond. Got lost a couple times on the way back and was aided by a friendly pair of hikers. Skirted some private property on the final leg, but I would have been better off sticking to the meadow walk to reach the woods near Mt Misery again. A good pace due to flat ground and level paths.
