Down where the Cut River slips under the road toward the Duxbury line the wind has nothing to slow it, and snow drifts across the pavement in long ribbons. MARINS CONSTRUCTION LANDSCAPING works that end of Marshfield all winter, plowing drives, clearing walks, and going back for whatever fills in behind you. In warmer months the same properties get mowing, edging, trimming and the seasonal cleanups that keep a yard from getting away from itself. Coastal ground is unforgiving and rewards steadiness above all. Finishing a route with the sky just going gray and every drive open is its own kind of good day.
