That's sweet man, i've been trying to do the same thing for a few years now. Longboarding and skateboarding alike are great and they both have their respective qualities just like skiing and snowboarding. Why do you think that so many people including myself love to snowboard? Because it takes a different skill set and it provides a different feeling all together.
Lay the fuck off this kid, what he's doing is great and you wish you had enough coordination to do what he does.
