By September the residential streets of Brighton go soft in the evenings — sidewalk chalk fading, sprinklers off, the grass finally growing at a pace a person can keep up with. Davids lawn care service works those streets, mowing and trimming, edging along the drive, clearing the leaves before the ground locks up. Then winter runs the route in reverse: shoveling steps, plowing drives, opening a walk wide enough to actually be a walk. A neighborhood looks after itself best when somebody is out in it early. That is most of what this work amounts to.
