Hopatcong yards are built on glacier leftovers — gray outcrops shouldering up through the grass, thin soil, roots doing what they can. D & V Landscaping mows around all of it in the thick of July, when heat sits still in the Northwood streets and the cut has to be timed right to keep turf from scorching. Mowing, trimming, edging, cleanups: a plain list, carried out on ground that is anything but plain. There is real satisfaction in a border cut clean against stone. By evening the yard reads as tidy and the ledge just looks like it belongs there.
