By midday the sun stands over Echo Lake and the cleared yards along its road go bright enough to squint at. Marin Landscaping keeps the mowing, trimming and edging going through that hour in Mount Desert, holding grass at a height that can take both the glare and the fog that rolls back in by four. Lawns carved out of the island's spruce need a light hand — a little more blade left standing, a definite boundary where the woods begin. There is pride in an edge that looks drawn rather than mown, and in a yard swept clear of grass before the truck pulls out. The same lawns get their cleanups as the season turns, so nothing accumulates and nothing gets away.
