An edge is the difference between a lawn that has been mowed and a lawn that has been finished — the clean line where grass stops and the walk begins. Sharpest Edge Landscaping is named for it and works to it: cutting, trimming, bed lines recut so they hold their shape through an August of heat and thunderstorms. When the season turns, the same crews take on Montvale's winters, plowing driveways and lots and salting walks so nobody has to guess where the pavement is. There is pleasure in both versions of the same act, drawing a straight line and keeping it, whether against turf or against snow. The town wakes up to it either way.
