Graniteville still keeps the color of the ledge it was named for, grey stone showing under the grass, and the yards in that corner of Westford grow over old quarry ground. A-1 Tree & Landscaping Co works those lawns straight through the mowing months, cutting even passes and finishing the borders so the turf meets the walk in one unbroken line. Cleanups come twice: in spring when the maples let go of their seed, and again in November when the oaks finally give in. Then the plow goes on, and the same driveways are opened before the first car of the morning backs out. It is ordinary work done attentively, and you can read it from the road.
