How about the guy that has the other show? On discovery channel. I think his name is Lee Stroud, beats Bear Gryllis by a long shot, the guy even carries his own camera equipment and actually stays out there, unlike Bear and his crew. Look at this video of one of Bear Gyllis' classic trips, clearly shows the hoax.
