East of the houses the Muskegon State Game Area runs out into oak and marsh, and the lawns bordering that country have deer prints in them by morning. MRJ Outdoor Services mows this edge of Dalton Township, where kept ground meets wild ground and the line between them gets drawn by hand every week. Dusk is a good hour for it — the air cools, the whine of the trimmer carries, and a yard comes back into shape while the woods go dark behind it. They hold grass at an even height, clip the corners and blow the drives clear, so a property reads as tended right up to the point where the trees take over. Lawn care out here is a border kept honest.
