At three in the morning out on the Mill Plain side of Danbury a storm is mostly sound: the scrape of steel, a truck backing up, the sodium glow over Federal Road full of falling snow. DSL LANDSCAPING SERVICES LLC works both halves of the year here, clearing snow while the city sleeps and cutting grass once the ground thaws and the hills go green again. Danbury sits high enough in the western Connecticut uplands that a coastal system can fall as rain down along the Sound and as half a foot up here, so winter asks for attention at odd hours. The payoff is plain and worth naming: a driveway opened before anybody needs to use it, and a lawn held even all summer long. Same crew, same properties, cold months and warm.
