South of the city the land goes flat and open, sugar beet fields running to the treeline, and the wind moves across a mowed lawn the same way it moves across a crop. Mid Michigan Lawn Care works that middle of the state — mowing, trimming, edging and yard cleanup for homes throughout the Saginaw Valley. In July the heat sits heavy and the grass wants cutting twice as often as anyone expects, so the answer is turning up on the day, in the sun, with sharp blades. A big flat sky makes a straight mow line look even straighter, and that is not nothing. By late afternoon the day's yards are all wearing the same clean finish.
