In July the breeze comes up off Great Egg Harbor Bay in the afternoon and the whole township exhales a little. Flanagan Sprinklers LLC spends those long days on lawns around Bargaintown — mowing, trimming, and the ordinary upkeep that carries a yard through the hottest stretch of an Atlantic County summer. Coastal grass takes a beating in August: sun from every angle, sand underneath, salt riding in on the wind. Keeping it green comes down to showing up on schedule and cutting with a light hand, week after week, until September turns kind again. A lawn that came through the summer looking well is worth standing back to admire.
