Morning in Amesbury comes off the water first — fog sliding up the Powow, salt air drifting in from the Salisbury flats, and a low gold light that finds the brick mill walls before it ever reaches the grass. Professional Mowing Services works in that light, cutting lawns along the hill streets and the river-bottom yards, keeping the growth answered week after week while the Merrimack valley does what it does: rain, heat, a hard green push all summer long. There is a real satisfaction in it — the clean line where turf meets walk, the striping laid straight across a slope below Powow Hill, a yard that looks cared for from the sidewalk without saying a word about it. They mow and maintain lawns for Amesbury and the nearby towns, the ordinary rhythm that keeps a place looking like somebody loves it.
