On a Saturday in June the carousel is turning down at Silver Beach and every backyard in St. Joseph has somebody in it. Lawn Hero keeps those yards ready for the weekend — mowing on a schedule you could set a watch by, trimming the fence lines, edging the drive, and clearing beds so the grass has room to run. There is a quiet satisfaction in pulling away from a lawn that has been cut, blown clean and squared to the sidewalk. Kids run barefoot across it, dogs sleep on it, grandparents look out at it, and not one of them has to wonder how it got that way. That is the whole idea behind the name.
