This is professional snowboarder Steve Klassen and his two-year-old daughter, Kinsley. She's the one hanging upside down by one arm.
It was Kinsley's 3rd birthday, so father Steve decided the best way to celebrate was with some tandem snowboarding. The result is this twist-and-trick filled video that may have some parents feeling queasy. There's already a lively YouTube comments section about the video. (Isn't there always?) But we'd love to hear your thoughts. Do you think a little child should be carried down a black diamond? Is 3-years-old too young? Is it all good fun? Let us know!
