The ground northeast of Howell does not lie flat — it rolls in glacial ridges toward Hartland, and every ridge means a driveway with an opinion about ice. Highland Services, LLC plows that country, taking the grades on the right approach, opening turnarounds wide, clearing walks and entries down to something a person can stand on. Hills change the whole calculation: where you stack the snow decides whether the next thaw runs down the drive or off the side of it. There is genuine pride in a hillside drive that is passable at six in the morning while the wind is still going. Winters here are long, and that is precisely the point of the work.
