The harbor here is deep and calm, tucked in behind the long arm of Harbor Point, and on a still morning the water holds the whole town upside down. North Shore Lawn Works starts its days along those shore-side streets — cutting, trimming and edging lawns that sit within earshot of the halyards. Grass this close to open water takes the wind and the sand and the cool nights, and it wants a steady hand more than a heavy one. Seasonal cleanups round the year out, lifting spring's litter and autumn's leaves so the turf goes under snow clean. The work is plain and the result is not: a crisp edge, a level cut, a yard that sits right in its setting.
