You've got to check this out. This guy is a nut. He's using the two weeks between Aussie tour stops to go snowboarding in Tahoe, build a foam pit to learn a back flip on a motocross bike, ride the celebrity races at both the LA and SF Supercross events, go snowmobiling and who knows what else!
Oh...and he's a pretty good wakeboarder too!
