At noon in July the cul-de-sacs off the ridge go still — deep shade under the maples, everything beyond it bright and humming. Juan Perez Lawn Service works straight through that hour: mowing, trimming along fences and beds, edging the walks, mulch refreshed, hedges held in shape, cleanups when the seasons turn over. Park Ridge lots sit neat and close together, so the difference between a lawn cut and a lawn kept shows plainly from the next driveway. The finish is the point — even height, borders cut sharp, clippings off the sidewalk before the truck pulls away. Small yards, done all the way into the corners.
