On Swans Island everything arrives by boat, the fuel and the parts included, so the mowing gets done with a certain economy of motion. Allen's All Season Lawn Care cuts the lawns above Burnt Coat Harbor and along the roads that run out toward the light, where the fog can close in by noon and lift again by three. Island grass grows short and salt-tough; it takes regular mowing, careful trimming around ledge and granite doorstep and stacked gear, and a cleanup each spring once the winter litter comes off. A trimmed yard with the harbor behind it and the boats swinging on their moorings is a fine thing to stand back and look at. Swans Island through the growing season, house by house.
