Before dawn the wind comes off Pleasure Bay hard enough to push snow back where you just took it from. RYBO Snow Removal plows South Boston's driveways and lots on that schedule, shovels the steps and walks, and lays salt where harbor damp makes everything freeze a second time. A blizzard here is never one job; a cleared apron can drift shut inside an hour. So the truck goes back out, and out again, until the ground shows. Cold work, early hours, and the small triumph of a street where everybody gets to leave on time.
