"Since we have a Baseball thread, why not Ice Hockey?"
"Because the world 'hockey' sounds sillier-and-sillier each time you say it, Don."
"Oh."
I had *no* idea that this sport was played indoors as early as 1875 (and in the Olympics since 1920). There is a bevy (I've always wanted to use that word, bevy) of interesting information in the Wikipedia article (under the "Ice Hockey" link), and Wikipedia's links will take you into even more depth.
Like the Baseball thread, this is about the sport itself - its origins, rules, etc. - and not about any particular team or player. Thus, it probably won't get a lot of activity, but it's here if you need it.
