Whats Hockey? Is that a Canadian thing? I can imagine a bunch of grown men chasing a little black flat thing around an oval for hours on end and that makes me think hockey. Thats not what your talking aboot right? It cant be something that needs either arctic outside temperatures or a ton of energy to keep it cold enough to freeze a inside arena. If hockey is what i think it is is should be banned by the UN's climate change committee for using too much refrigerant.
