Yep, that's how some of them are are.
Especially Travis Rice, who happens to be in that movie. His Supernatural contest convinced me that he's a "spoiled little douche". I bet he likes rusty spoons.
There are others, though, who are actually really nice and smart people...
Such as Scott Stevens and Jeremy Jones, who are my 2 favorite pros.
Stevens is cool because he's just a flat-out decent person who's not trying to show off or anything, just have fun. He has a great attitude, and at the same time he's by far the best urban/park riders I've ever seen. I swear he's a jedi or a ninja or something.
Jones is also awesome because he doesn't just rely on a helicopter to get around and to him it isn't just about tricks. He actually hikes and climbs the mountains, and then sends it. He's in it not just for the shredding but everything else: the adventure, the backcountry, the friends, the memories. He is a true backcountry rider.
Art of Flight has nothin on these guys!
