Troupsburg sits high on the Pennsylvania line, where the hardwood ridges run south and Troups Creek finds its way down through them. Lawns up here are carved out of hill and woodlot, and they want someone who doesn't mind a grade or a quarter-mile driveway. Young Hickory Landscaping mows, trims, edges and clears the season's litter — sticks after a wind, leaves once the maples let go. The reward is the moment a yard resolves out of the treeline: cut, squared off, the woods held politely at the border. At this elevation the air stays cool into June, and the grass keeps coming right through it.
