Because some people's adrenal glands demand more use than others, this is a video of the Flying Frenchies surfing and base jumping from a zipline in the Vercors Massif mountain range. They reach speeds past 45MPH before hopping off the board for a 2,000 foot drop to the ground below. Admittedly, if this were a ride at an amusement park, I would want to ride it. Probably with a belly full of funny cake and candy and soda. I've patient zero for Type 3 diabetes.
Keep going for the video.
Thanks to Doug, who agrees if these guys were real extreme sporters they would have attached a rocket to that surfboard.
