A couple writers (this one included) spent three weeks on a commercial salmon vessel based in Naknek, Alaska, to raise awareness and funds for the Greater New Orleans Foundation, a charity helping victims of the Deepwater Horizon Gulf Coast oil spill. They did their ad work and their fishing work while there. In all, it was a lot of work.
The trip was documented in real time on a blog with post, weather updates, and a fish-o-meter. Merchandise was sold and all proceeds went to the GNOF.
