A shop like this one keeps odd hours in a storm. McIntyre's Lawnmower & Locksmith Shop turns to snow work when Westfield goes white overnight — clearing driveways and walkways, opening the apron at the end of a drive that the town plow just filled back in, putting salt on steps and paths where ice hides under a half inch of powder. There is a mechanic's habit in it: start early, keep the machine running, finish the block. By the time the storefronts along Elm Street have their sidewalks swept and the coffee is on, the houses on the route are already open to the street. Winter mornings make their own argument for getting up in the dark.
