Cool - do they really get all physical and moer each other? 
Must physical no rules game on earth. 
Yup, makes boxing look sedate. I once saw a guy shouldered so hard that he hit the Perspex boards with enough force to rip them out of their mountings. This was in Toronto, game was against Buffalo City.
What struck me is how well the entire setup is run. The centre is a sort of mini-mall, with lots of shops, great atmosphere, loud, but no loutish behaviour. Really enjoyed it. It's just so fricken fast, you cannot look away for a split second!
For interest sake, to qualify for a season ticket (at least for the Toronto games), you have to put your child's name on the list right after birth. He/she may eventually get to the front of the waiting list by the time they're 40 or 50... Almost all games are fully sold out - the Canucks love their hockey!
