My friend has a skateboard as well, and sometimes when we're walking to class he'll zip past us leaving us with "catch you guys later"...lol. But I don't think he is that good with it to do those tricks yet, lol. Maybe in a few years haha.

Sometimes it just gets weirdly interesting when you start to think of the physics involved with these tricks, but I think that's just the side effect of me studying physics for multiple semesters straight... :3
