Every small town has a sound in July, and in Plano it is a mower somewhere down the block, working its way toward you. Lindsey The Lawn Lady keeps a route through those streets — the older squares near downtown under their big shade trees, and the wide open lots out toward the fields where the sun never lets up. The work is mowing, trimming and edging, week after week, and the pride is in consistency: the same clean line at the curb every single time. Grass here grows hard through a humid Illinois summer, and staying ahead of it is its own kind of steadiness. Come Friday, a whole street can look cared for at once.
