Main Street in Winterport runs a line of tall old sea-captain houses above the Penobscot, and their lawns slope down toward the water as though leaning in for a better look. DJ Williams and Son Landscaping LLC keeps that slope in trim — mowing, trimming close along steps and stone, edging the walks so each house sits clean on its own ground. Spring cleanups clear the winter's sand and broken branches; fall cleanups handle the maples, which take their time and then let go all at once. On a July afternoon with the river flat and bright, a freshly cut lawn on that hill is a fine thing to stand and look at. Winterport is worth the effort.
