Summer evenings on Oxbow Lake come with a long gold light that lies flat across the yards and makes every mower stripe show. Dna services cuts into that light — the last passes of the day laid down in clean parallel bands, the edges trimmed tight along the walk, the clippings blown off the drive so nothing tracks inside. Lawn care in White Lake Township means keeping up with grass that runs fast on the low damp ground near the water and slower on the sandy rises a street away. The work is simple and it is never finished, which is part of why it satisfies. A cut lawn at dusk, still cool and smelling green, is a small good thing to leave behind.
