A garage learns winter early. Norwood Auto Care watches a forecast the way it watches a temperature gauge, and when snow is coming the plows go on. Driveways and lots get pushed open, walkways cleared, sand and salt spread on the ice that forms overnight at the bottom of a sloped drive. There is something plain and good about a customer stepping out to a cleared apron and a car that starts and goes. Norwood first, then Westwood, Walpole, Dedham and Canton as the storm allows.
