Late March in Epsom loosens everything at once — the Suncook runs high and coffee-colored under Route 4, and every yard between the traffic circle and the foot of McCoy Mountain comes up soft and buried in a winter's worth of pine needles. That is TNT Landscaping's kind of morning: rakes and mowers and brush saws working a property back down to its stone walls, the first cut of the year laid in straight lines. By January the same trucks are out ahead of the school buses, clearing the storm off dooryards and long gravel drives while the pines stand loaded and quiet. It is plain, physical work, and it leaves a plain, satisfying mark — an edge you can read from the road, a driveway open before dawn, a piece of New Hampshire ground kept the way its owner wants it.
