The wind off Long Island Sound reaches down over the Kings Park bluffs and into northern Smithtown before most of the neighborhood is awake. Breakaway Lawn Maintenance likes starting there at six, when the air is still moving and a mower leaves stripes that hold their shape all day. The routine is unglamorous and exacting: cut, trim the perimeter, edge the drive, sweep the walk, move on. Twice a year the crew changes gears for the big cleanups, hauling out winter's debris in spring and the leaf drift in November. What stays with a homeowner is the sight of it at dusk — an even lawn with a sharp border, nothing shaggy at the fence line.
