I've tried surfing with my buddies once, but nobody wanted to show me how to do it. The waves threw me around and I felt like a complete fool for a while. It was fun.
But the scary thing was that there were these giant rocks all over the place, and the waves were just trying to hurl me into them.
Someday I would love to really learn to surf, but I just don't live close enough to good waves right now to get into it. I waterski/boogyboard/drive fast in a boat when I need my sea-thrill fix.
