I went to a Habs Bruins game in Boston around 10 years ago. What a freakin' zoo, some Bruins fans were heckling Saku Koivu about his cancer, calling him a f@ggot AIDS victim. I won't even get into their "interaction" with Habs fans but I'll say it was worse than what I saw in Philly.
Anyone singling Canucks fans out for bad behaviour should stop talking out of their asses. Unless they've been to other arenas, they don't have a clue what they're talking about. I've been to every Canadian arena and about half the US ones.
