New York City received another dousing of snow and sleet yesterday. School children enjoyed the day off while adults were outside shoveling snow so the cars could get out.I saw this salt spreader on the sidewalk in my neighborhood. The workers were still shoveling snow further up the street. I assumed that once the snow is cleared, the blue colored salt will be deposited on the street via the wheel barrel looking machine.
Does anyone know what the salt is blue?
