Don't believe the history, nostalgia hype about Madison Square Garden. Don't fall for it please. And as others have said, save your money. And if you've noticed, the examples from the NYR-Pens rivalry were from years ago.
4 different buildings called "Madison Square Garden" have been built all at different locations throughout Manhattan and 3 of them have been demolished, except for the current hideous one, built in 1968, which despite the millions and millions spent quite recently to refurbish it on the inside, still looks like one giant monstrosity from the outside.
People from out of town mistakenly think it's like a Boston Garden/Montreal Forum/Maple Leaf Gardens/Chicago Stadium, etc. It is not. It's not the same original building that has been sitting there for like 80 years, oozing with history.
And the inside still is incredibly overrated and the atmosphere isn't as incredible as pretentious New Yorkers would lead you to believe.
Skip it. Plenty of more exciting non-hockey things to see throughout NYC with the money you will save from what would be a totally unnecessary visit to a building that hypes itself as the "world's most famous arena". What is so famous about it anyway?
Sabres-Devils would be a better game anyway.
Well damn - not sure what to think then.
I'm actually totally relying on you guys on this one. I literally know nothing of New York/New Jersey and the experience at the ice rink.
