They could have built several very nice wave pools with the money spent on the opening ceremonies. I have always thought water polo would be more fun to watch in a wave pool, give them a real reason to wear those sissy helmets.
apparently youve never played water polo before because if you had, you would know that its one of the hardest sports you can possibly play. playing in a wave pool would be near impossible considering you're fighting to not be drowned by your defender. water polo is a constant battle for position (especially playing in the hole)...they wear the helmets to protect your ears from having them ripped off in a struggle (much like rugby). ill hop in the pool with you and you can try to tread as i lay my 6'4" 210 lb. frame on you while kicking and punching you underwater, and the guys that play on the olympic team run much bigger than me (6'5" 230 range)...oh yeah and you cant use your arms to tread because i get to hold them down so you cant get the ball...then ill whip a shot at your ear so your ear drum explodes due to the sudden pressure put on your ear by the ball without that "sissy" helmet to cover your ears
