It's snowing in Chicago!  Come play in the snow at the Chicago Park District's fourth annual Polar Adventure Days on Northerly Island(1400 S. Linn White Drive).  View winter camping displays, ice sculptures and shake paws with a Siberian Husky.  Put on a pair of snow shoes and take a hike, make some crafts and if you are one of the first 500 visitors have a free cup of hot chocolate.
