On a July Saturday the neighborhoods off Portage Avenue wake up slowly — a sprinkler, a screen door, somebody's radio — and the mowers start early to beat the heat. Lopez lawn care moves through those streets on a set rotation: cut, trim the fence lines and around the trees, edge the walk, blow the drive off, gone before noon. Beds get mulched in spring; leaves get cleared when the maples turn along the side streets. A lawn kept on a schedule holds its color and its shape, and the difference reads plainly from the sidewalk. Three Rivers and close-by towns including Constantine, Centreville and White Pigeon.
