surfing

It's still early days for this sport; the skis look budget and the skill set isn't there; but you can definitely see the potential in what these guys are trying to do.

This is obviously going to be a pretty specialized sport with the jet ski requirement but, with a paddle, it could become more popular (like stand up paddle surfboards are now). There looks to be good potential with the kite surfing/ skiing too.

Sport can progress quickly... mountain biking didn't really get going until the late 1980's and look at it now at the: red bull rampage
