Stand at Marine Park on a May morning and the Navesink throws light back up into the trees, and half the town seems to green at once. Chace Lawn Care LLC works the streets behind that waterfront — mowing, edging along walks and drives, cutting mulch rings clean around the beds, and carrying off whatever the season sheds. A finished lawn has a particular look from the curb: even height, a straight line where grass stops and pavement starts, no ragged fringe at the fence post. Getting there is unhurried, ordinary work done the same way each visit. The river keeps these mornings cool a while longer than inland, which is a kindness to anyone pushing a mower.
