Castine keeps its own weather: fog off the Bagaduce in the morning, the light off Dyce Head in the evening, and elms leaning over brick sidewalks in between. Mariner Property Services tends the lawns under those trees — mowing, trimming, edging along the old walks, and clearing leaves out of the village's short, steep front yards each fall. Winter on the peninsula means plowing driveways, shoveling entries and sanding where cold and salt spray turn a walkway to glass. In a place this compact, a cleared path and a level lawn get noticed by everyone who walks past. That is a fair reason to do the work carefully.
