The North River runs slow and dark through Hanover's pines, and after a storm the whole corridor goes silent under white. Mass Landscaping Inc plows the driveways and clears the walks that thread off Route 53 and out along the back roads toward Luddam's Ford. South Shore weather often starts as rain and flips over at the worst possible hour, which makes timing the routes half the craft. There is a moment at first light — pines loaded, the drive scraped clean, the truck idling — that squares the whole cold night. Getting people out of their own driveways is the plainest sort of help there is.
