Out along the Bungay River the back roads of North Attleborough heave and settle with the frost, and winter shows up in the ruts before it shows up in the forecast. Groundrules Excavating and Snow Removal handles the snow side of that season, plowing driveways and lots, clearing walkways, and putting down salt and sand where the cold holds longest. Long drives and awkward turnarounds are their own puzzle; the snow has to go somewhere that still works in March. When a storm runs all day it gets worked in stages, so nothing ever gets ahead of the blade. The result is unglamorous and exact — pavement you can see, and a way out.
