Some mornings in May the fog sits on the Quinsigamond over in North Grafton until the sun burns a hole straight through it, and every lawn in town wakes up soaked and ready to grow. Ryans Landscape Construction runs the whole green season out of that starting gun — mowing, edging, string trimming, mulch, and the cleanups that bracket April and October, week in and week out. When the light gets short the equipment changes and so do the routes: plowing driveways and lots, shoveling walks and entryways, salting and sanding once the wind swings around to the north. The pleasure is in the finish, whichever season it is — a straight edge along a walk, black pavement in a white town. Grafton keeps both lists full.
