The best part about it is that here was nothing to yell about. Even though the video was shit, I didn't see any punches. From the way that bitch was yelling, you would have thought her son had just been raped in public.
The parts they lay down are frozen sheets of ice. They lock together like a puzzle. Kind of like a basketball court. Then the zamboni comes over it (I think it made two passes...) and it's smooth like one flat sheet. It's pretty awesome.
