On the side streets of West Dearborn the silver maples hold the early light a while before letting it down onto the grass. A2 Lawn and Gutter Solutions LLC keeps those yards on schedule — mowing, edging, trimming, and carrying the clippings off so nothing is left behind but the smell of it. There is a particular satisfaction in the line where a lawn meets the sidewalk, cut so straight it looks drawn. Summer here runs long and humid, and the grass answers every storm that rolls in off the flatland to the west, so the route keeps moving. By evening the whole block reads as one continuous green, house after house, and that is the point.
