4 Small Rivers

A lovely day for a walk ... and so out to the old family stomping ground of Concord, and to the Great Meadows National Wildlife Refuge. Not a tremendously solitary experience: dozens of avid birdwatchers, lugging heavy binoculars or cameras on large tripods. (And the roar of jets from the Hanscom Field Air Base? Field?) But a beautiful day, toads croaking, redwing blackbirds making their distinctive cronk-a-dee sounds, geese honking and a few finches chirping.
