I've gone to several CC/UND games as well as DU/UND game at both the World Arena and Magness Arena. While generally speaking the crowds are friendly, they aren't too bright on the rules of hockey. The fans that sit around me talk about getting their nails done, what's on sale at Nordstrom, or about the Broncos quarterback situation. I'd recommend a trip out to Colorado Springs or Denver for any Sioux fan wishing to see good hockey (CC and DU typically play the Sioux well in their buildings; minor exception being DU last fall) as well as getting in some skiing up at Vail or Winter Park.
