Frozen Tundra Hockey Classic
The Frozen Tundra Hockey Classic was a college ice hockey game played on a makeshift ice rink covering the field at Lambeau Field in Green Bay, Wisconsin. The game was the second outdoor game involving US college teams, the first being "The Cold War". The matchup pitted the men's ice hockey programs from the visiting Ohio State University Buckeyes and the host University of Wisconsin–Madison Badgers. At the time, Ohio State represented the now-defunct CCHA while Wisconsin was a member of the WCHA. Both programs now compete in the Big Ten Conference. Sources
