Libertyville keeps its old oaks and its river, and on a Saturday morning half the town seems to be out on its lawns. Card My Yard - Libertyville, IL works those yards through the growing season — mowing on a weekly turn, trimming along fences and around the oak trunks, an edge cut along the walk and the apron. Under a big canopy the grass grows unevenly and collects everything the trees drop, so the clearing at the end matters as much as the cut itself. Autumn along the Des Plaines runs long and loud with color, and the leaf cleanups go right up to the cold. What people come home to is a yard that looks looked-after, which is the entire ambition.
