Averill Park sits where the Taconic foothills begin to lift out of the Hudson lowland — a country of pine ridges, back roads and small lakes, Crystal and Burden and Sand. Lawns here are carved out of woods; they run to shade, to slope, to a stubborn edge where the yard gives up and the forest takes over. S&S Lawn and Landscape keeps that line clean with mowing, trimming, edging and the cleanups a plateau full of oaks and white pines insists on. Summer mornings come in cool off the water and burn off by nine, which is a fine hour to be behind a mower out along Route 43. The result is a yard that looks deliberate against all those trees.
