When snowstorm after snowstorm pounds Boston, many of us get snow days. But not snow plow drivers. They're working overtime.
On Tuesday, 450 pieces of city equipment were on Boston streets, many of them treating the roads with salt. So far this winter, the city has used about 67,000 tons of salt (with 13,000 tons of salt on hand).
We tagged along with Erik McCormick, a city plow driver, Tuesday.
