Salt wind comes off the harbor early in Marblehead, and by the time the fog burns off the granite ledges the mowers are already running. Musso Landscaping keeps the lawns of this rocky seaside town — the narrow yards behind Old Town's clapboard houses, the green shelves of grass that somehow hold their footing above the tide. There is a plain satisfaction in a clean edge drawn along a stone walk, in a lawn cut close and even under the coastal light, in a yard left tidy enough to catch the afternoon glare coming off the water. Through the growing months they tend it — mowing, edging, and the seasonal cleanups that carry a yard from the first thaw to the last raked leaf — so the grass stays kept from the green of spring into the salt-bright turn of fall.
