It's three days of fun, and it started today. Detoit's Winter Blast will fill Campus Martius and surrounding areas in Detroit now until Sunday night, so bundle up the kids -- although the weather forecast on Saturday and Sunday looks a bit less February-like than the norm, at least during the daytime -- and get downtown to skate, eat, and more. This is one of those events that can thrill the little ones in your life, so take advantage.
