Plow drivers keep roads safe for motorists during storms
The sky is darker than a pocket when John Adam reports to work at 3 a.m.
His supervisor, Gary Kennedy, has likely been at work since 1, driving the district roads before he sends plows out.
Six inches of new snow greet Adam; four more will have arrived by the time he's made his first run north to Itasca State Park, plowing U.S. Highways 71 and 200 to the north side of the park and back.
