Shasta Boyz productions just released the fourth of seven trailers in their series Slippery When Wet. Ben Stookesberry, the 32-year-old pro kayaker, is the focus this time. Watch Stookesberry paddle record high water on Idaho's Payette River and race down California's Middle Kings in 17 hours. The Class V run's counted among California's hardest. To paddle it in 17 hours is something like climbing Yosemite's El Cap in one day. Enjoy.
