West of Burton the land opens toward Gaines and Swartz Creek and the sky gets enormous, the kind of Midwest horizon where you watch weather coming for an hour before it lands. Midwest Mowing Bros LLC works under it, mowing and trimming lawns across the city while the grass runs hard from May into October. Flat ground is honest ground — a straight line stays straight, and every wavy pass is on display until the next cut. So the lines get walked straight, the borders get cut, and the clippings get cleared off the walk. It is plain work done carefully, which on a wide green lot is its own kind of good-looking.
