I respectfully disagree. I've been to LA, Anaheim, Philly, Minnesota, and Florida. FLA and ANA are way worse and it's not even close. LA isn't far behind those two, even when winning (although a lot of this is a stadium architecture issue).
The crowd noise should be compared not to the top teams that are winning, but teams that have sucked as hard as we have. Think early 90s Red Wings and Senators and Bill Wirtz Blackhawks. We've got much better attendance and fan involvement than teams on that scale.
Besides, you know FNC will rock in perpetuity as soon as we win our first post-tank playoff series and all ails will be cured.
