Storms arrive over the Sourland ridge first, gray on the treeline above Hillsborough Township before a single flake reaches the flats. Doyle Brothers Contracting watches for that and goes out into it, plowing driveways, opening walks and putting down salt while the ridge road is still filling in. The lanes climbing toward the mountain are steep, shaded and slow to give up ice, which is exactly the kind of ground that rewards a careful pass. By first light the drives are open, the steps are safe, and the township can go about its morning. That is the whole ambition of a night's work, and it is enough.
