Out where Keansburg runs into Port Monmouth the streets go flat toward the marsh, and weather that hits one end of the borough reaches the other about four minutes later. LJ Property Services keeps properties along that stretch through both seasons — mowing, trimming, edging and yard cleanups in the growing months, then snow plowing, shoveling and salting when winter takes its turn. Houses, rentals and small lots all get the same rounds on the same schedule. What holds it together is simply showing up: grass that never gets away from anybody, a lot cleared before the doors open. Keansburg, Port Monmouth, Union Beach, Belford and Middletown.
