They just had an outdoor hockey game in New York, in weather much, much colder than predicted for Sunday.
Amazingly, the wheels didn't fall off, and people went to the game.
To be fair....I think you're comparing apples and oranges. It's safe to say that the fan bases at this game will be very different from the dooshnozzleesque crew of wine sippers at the superbowl. All it takes is one trip to a superbowl to realize what the NFL is all about. I have ZERO desire to ever go back to a superbowl ever again.
The similarities they DO have is that they are 'events'. And the Super Bowl trumps the heck out of an outdoor NHL game.
Thus far, it seems like weather won't be much of a factor. I think it's going to be a massive success, and New York might have another one in ten years or so. I think Seattle will get one.
I don't understand anyone that wouldn't be rooting for crazy weather, actually. So many great winter games through the years.
