Concord is built on granite — the ledge runs right under the north end of the city, and the old quarries are still up there in the woods. Keaton's Landscaping LLC works the ground on top of it: mowing and trimming through the season, mulch and hedge work, cleanups in spring and again when the leaves come down. Winter turns the same job hard and early, with plowing, shoveling and sanding on drives and walks that freeze fast in the shadow of a ledge. The reward is small and immediate — an open driveway, a safe set of steps, a lawn cut level as a table. Stone-country weather asks for steadiness, and the work answers it.
