Played amateur hockey for 15 years and loved it. Far & away, my favorite team sport to play. On a minute per minute basis, there is not a better workout than showing up for some pick up hockey. I stopped playing a few years ago but still have all my gear. We have a great two rink facility pretty close to me but I know as soon as I start playing, I'll want to get back into leagues and I already have enough expensive hobbies.
Tyler's right, it's a sport that doesn't translate well to TV, which is why their TV contract sucks.
Go SHARKS!
