The Des Plaines River threads south through Gurnee under cottonwood and silver maple, and the humidity it lifts into a July afternoon is the reason lawns here grow the way they do. Frank's Property Maintenance LLC works those blocks and the ones out toward the Warren Township fields, mowing, trimming and edging on a steady rotation. Riverside yards hold their moisture and grow unevenly; open subdivision lots bake by August. Reading that difference and cutting each one right is the craft of it. What the neighbors see is simply a lawn that looks composed, one week after the next.
