Before dawn Malletts Bay is a sheet of grey, and the only sound in that part of Colchester is a plow blade finding pavement. All Seasons Excavating Inc. is out in those hours, opening driveways and clearing lots so the first shift can get where it is going. Wind off the bay packs snow hard against garage doors and rebuilds the banks along the road, so the route runs a second time. Walks get cleared and the piles get pushed back out of the sightlines. Snow removal for Colchester and the towns around it.
