Hmm, Penn State does this for big football games and we were told to 'cease and desist' by the Colorado Avalanche because they were the first to do it as the Winnipeg Jets. We can still wear all white, but the term 'white out' is verboten.
You shouldn't have listened. The Colorado Avalanche used to be the Quebec Nordiques. The Winnipeg Jets (who originated the "white out") are now the Phoenix Coyotes.
