Ledge runs close to the surface around Quiambaug Cove, and you learn a property here by the places a blade can and cannot go. H&H Landscaping LLC mows, trims and edges those yards through the green months, then turns to plowing, hand-shoveling and sanding once the cove starts steaming on cold mornings. Stone walls, short slopes, drives that bend around outcrops — nothing about it is standard, so nothing gets treated that way. A cut lawn in August or an open drive in a February dawn: the aim is the same, a place that works. Stonington, Mystic, Old Mystic and North Stonington are covered.
