Fog sits low over the flats of Armada Township on summer mornings, and it burns off about the time the first mower drops its deck. Green Line Turf Services, Inc. spends the day laying stripes across lawns that run wide and open, the way yards do out here where the nearest neighbor is a field away. Mowing, trimming, edging, keeping the turf even and thick through the heat — that is the work, done again and again until it looks effortless. There is a particular pleasure in standing at the road afterward and seeing the lines run true. Good grass is a slow thing, and it is worth the patience.
