The weather comes up the valley from the southwest and you can feel it in Bangor a good hour before it starts. DAVE'S SNOW PLOWING answers it in driveways from Broadway out to Hermon and Glenburn, pushing back the wall the city plow leaves at the end of the drive and opening a path wide enough to back the car out straight. Nothing quite matches the sight of a driveway cleared down to the gravel while the rest of the street is still white. Plowing, driveway clearing, shoveled walks, and the return trip when the storm isn't finished with you. Winter here is long, and a cleared drive at dawn makes it a good deal shorter.
