I loved it - and the Flyers won in O/T.
It's something being at a hockey game. It's a brutal game and the Philadelphia fans are brutal fans. I was right in there too, cheering to see the Panthers goalie apparently injured. Yelling 'ASSHOLE' and 'YOU SUCK' in unison with several thousand people when the refs gave a crap call - or didn't call against the Panthers when they should have. There's nothing like it.
Of course - it all starts with 'The Star Spangled Banner' and (of course) everyone stands. All 19,530+ Americans. We all cheer when it's done, too. Then we all yell at the players (our own and the opposing team), the refs - whoever!
I love being an American. I especially love being an American in Philly.
