It will take a lot of ice to transform Busch Stadium for 2017 NHL Winter Classic

ST. LOUIS, MO (KTVI) - What does it take to turn Busch Stadium into the site of a hockey game? For one thing, it will take a lot of ice.

The NHL officially takes over Busch Stadium Thursday to begin setting up the ice rink for the 2017 Winter Classic. The Blues and Blackhawks will face off there January 2nd.

A 53-foot trailer, housing the world's largest mobile refrigeration unit, arrives at Busch Stadium Thursday to begin the set up.
