Your national pastime is baseball, ours is hockey. As you say you get interested in baseball when its in the world series. Im not a die hard fan anymore but I still get interested when my team plays.
Its a game that many canadians were brought up playing, and were just naturally raised to love it.
Your reference of not being able to see the puck is amusing as, last time i watched...(was a while ago thanks to American greed)... the camera followed the puck for the most part. Also, as you say the puck is black, with usually some colourful design on it, depending on where you are, and it is moving on a white backround. I really do not see how hard it is to see it under those circumstances. Also, that idea, or one similar to it was tried in the past in America but was eventually thrown out because it was pointless.
