By four in the afternoon a breeze comes up off Great Egg Harbor Bay and takes a few degrees out of Northfield, and that is the good hour to be cutting grass here. McLandscaping runs the streets from the Linwood line back toward town on that schedule — mowing, trimming around posts and beds, keeping the finish crisp where lawn meets sidewalk. Summer on the mainland side of the shore is humid and fast-growing, so seven days is exactly the right interval and skipping one shows. Spring cleanups open the year and fall cleanups close it out. In between, the reward is simple: pull up, do it right, leave behind a yard somebody is glad to come home to.
