Wave

This picture mesmerizes me. I just look at it and wonder: How did they all get out there? Are they all there to surf that giant wave? If so, why are they all just watching? Do they have to take turns? How do they decide who goes when? Are they scared, excited, bored? Is the photographer on a boat or standing on a surf board or what? Is it dangerous to just float out there? Could I go there to just float and watch?
