Winter comes into Saratoga Springs from the northwest, down off the Adirondack foothills, and it almost always comes at night. Salvadore Services LLC keeps those hours, plowing driveways and clearing lots while Broadway is still dark and every streetlight wears a cone of falling snow. Salting and sanding follow the blade, because a surface scraped clean and then left to glaze over is only half a job done. There is a real satisfaction in a driveway squared to the pavement with the banks pushed back far enough that the next storm has somewhere to go. By the time the first headlights swing out toward the Northway, the way is already open.
