Allow ice skating on approved surfaces only (call your local police department for a list). You should also counsel kids to stay out of snow banks and advise against building tunnels and forts. The former may be the target of city snowplows that will have no clue a child is burrowing inside; the latter can collapse with catastrophic consequences. In 2008, an 8 year old New Brunswick, Canada, boy suffocated to death when a snow tunnel he had built caved in on him. To head off danger, enforce a strict buddy system at all times.
