In 2009 the Blackhawks stepped out their home stadium at the United Center and suited up to face off against the Detroit Red Wings at Wrigley Field (And no, that wasn't a typo). This special game staged by the NHL took place outdoors inside a snow filled ballpark. Even the rules of the game were changed slightly to account for any possible adverse weather conditions at Wrigley Field. The teams changed sides at the first whistle after the halfway point of the third period. If you were lucky enough to have a ticket, it was a Blackhawks experience that will never be forgotten. These Blackhawks Winter Classic pictures capture some of those moments.
