Salt rides the breeze off Mount Hope Bay into Swansea, and on a July afternoon you can taste it from Ocean Grove to the marsh grass along the Cole River. Lawns this close to tidewater stay lush through damp mornings and want cutting on a steady rhythm. AJI Outdoor Services cuts and edges Swansea yards, carrying the green out to the split-rail fences and the beach-rose hedges. Even the town hall here is a small stone castle, and a trim lawn around an ordinary cape borrows some of that sense of occasion. As the sun drops behind the marsh, a freshly cut yard smells like summer in a shore town.
