The Blog That Yost Built came across an interesting tidbit in the Detroit News, regarding Wisconsin holding an outdoor hockey game.
According to the News, Wisconsin will be making a formal announcement regarding an outdoor hockey game next February at Camp Randall stadium in the next two weeks. The Badgers have been trying for some time to schedule an outdoor game at Camp Randall. A deal to play a WCHA game outdoors fell through, so it's likely the game will be played against a non-conference opponent, with Michigan being one of the rumored schools.
I'd expect an announcement to come in the wake of tomorrow's outdoor hockey game between the Detroit Red Wings and Chicago Blackhawks at Wrigley Field.
