Minnesota has been looking like the North Pole thanks to a wintry blast that is slamming into the U.S. Freezing cold wind blanketed the roads with snow and ice, making driving treacherous.

Teens are stripping down to take "The Snow Challenge." Videos are popping up all over YouTube of teens stripping down to their undies. It looks like fun, but watch out for frostbite!
