East Gloucester's streets tip straight down toward the water, and in February a half inch of glaze turns them into something you respect. MJ Briguglio Masonry & Tile takes on the snow work there — plowing drives, clearing walkways and steps, shoveling out around the cars, and laying salt and sand where the pitch gets serious. Storms that cross the harbor come in wet and then freeze hard overnight, which means the second pass matters as much as the first. There is a plain kind of pride in a steep East Gloucester driveway scraped to bare pavement while the roofs around it are still white. Rocky Neck goes quiet in winter; the work does not.
