Nashua keeps its dooryards close — a strip of lawn between granite step and sidewalk, a low stone wall gone soft with moss, the road tipping downhill toward the brick mills and the river. Lone Wolf Landscaping, LLC works those yards and driveways, mowing through the long green weeks and clearing snow when the valley goes white and quiet. There is a plain pleasure in grass cut to an even nap, the last pass laid down straight along the walk, the edge crisp where turf gives way to pavement. And there is another kind of pleasure at four in the morning, headlights full of falling flakes, a driveway opened end to end before the neighborhood stirs. Around Nashua and the towns beside it, that is the work: a yard that carries its season well, and a clear way out to the road.
