Noon in July, and the fields at the edge of Dorr shimmer a little at the far end. Northwest Turf works straight through it, mowing at the height the heat calls for, trimming borders, edging walks, reading each lawn for the dry patches that always show up first along the driveway. Grass in this part of Illinois will take a beating in August and come back green in September if it is handled right during the hot weeks. That is the craft, and it is mostly patience plus a sharp blade. Lawn care and turf maintenance across Dorr Township.
