Have to disagree with this in regards to pro snowboarders.
While some pro snowboarders can let the fame go to their head, a huge majority of the pros I've met are chill, laid back guys.
Most snowboard pros work a second job and are just your average local living at a ski resort. Don't confuse the small minority of pros earning big money with the rest of the pro snowboarder population.
I'm not surprised to hear this, I know a few pro sailors and they're generally solid dudes. similar thing, fringe sport.
