Midsummer heat lifts off the pavement in the alleys behind South Moline's houses, and everything green pushes hard through July. Guerrero Landscaping & LawnCare works straight through it, mowing, trimming along fences and foundations, edging drives and sidewalks, and clearing away what the cutting leaves. Edges are where a yard is won or lost, since a clean line at the concrete makes an ordinary lawn read as finished. The trimmer goes into the corners no mower can reach, and the walks get blown clean before anyone leaves. Nothing showy in that, just a property that looks squared away.
