Late August in Downers Grove brings the first night cool enough to open the windows, and the grass, which has been sulking through the dry weeks, comes right back. JIM'S LANDSCAPE & LAWN CARE, LLC is on the same weekly rounds it has kept since spring — mow, trim, edge, clear the drive. The parks fill up again about then, and the residential blocks near Doerhoefer get plenty of foot traffic past the front yard. Nobody stops to praise a lawn that looks right; they only notice the one that doesn't. Working toward the version nobody notices is its own kind of pride, and it carries the route straight through leaf season.
