The technology park off New York Avenue empties out at night, and when it snows the drives out there go blank and unmarked. Metrowest Landscape & Construction Inc is into it early — plowing driveways clear, shoveling walkways and entries, spreading salt and sand where the ice sets up hardest. A storm is not one job but several, so the route runs again while the snow keeps coming. Framingham can hand you eight inches overnight and freezing rain on top of it. Clearing it well, over and over, is the work.
