A sunny day to begin with on the Greenway! You can see why this was an old railroad track- straight as far as you can see for miles…not too much fun but at least not on roads again. Off to side were a few interesting attractions, Chair Falls and Concord Community garden. Got off Greenway for good at Environmental Learning center- seemed promising until we realized it was closed, but we were totally surprised by BIG telescope up top! WHO KNEW? Really have to look into this more. Unfortunately left park and joined roads for the rest of the hike. Highlight was a ‘Flintstones’ house on a back street- looks just like you would imagine- very organic- once again proving hidden treasures can be found off the beaten path.
