Today, took a chilly, damp six-mile ride on the river trail in Watertown/Waltham/Newton. Was delighted to see a plethora of wildlife in the rain. Many waterfowl - geese, ducks, a swan, a couple of cormorants. A great blue heron and a large flock of gulls feasting below the Watertown dam. A couple of red-winged blackbirds darting through the rain. A rabbit, a muskrat paddling along by the footbridge near Stop & Shop, and below the footbridge, a group of 3 or 4 very large carp.
