Storms reach Scituate from the west, over the Connecticut line and the Ponaganset hills, an hour or two before Providence ever sees them. MCM Landscape Management Inc watches that sky for a living — plowing driveways and lots, blowing out walkways and steps, treating ice where it sets up hard under the trees. The roads through Rockland and Potterville climb and drop, and a driveway on a grade wants a different pass than a flat one down in the village. There is pride in a plow line laid clean to the pavement, and in a set of front steps someone can carry groceries down without thinking twice. Come the thaw the work goes quiet and the hills go back to being hills.
