I would love to see the half-pipe in the 2010 'lympics, it would be one of the sickest ways imaginable to show the world the sport of freeskiing.
A separate event, if probably organized, advertised, and funded, would be crazy ill, especially if it was also held in the Vancouver/Whistler vicinity during the 2010 Olympics, or maybe afterwards.
The world definitely needs to see more of this sport, which is progressing like crazy but still held within a small community. In a way, I like it, but I hate how people who have never skied or snowboarded before immediately go "skiing is gay, snowboarding is cooler".
