Offroadx posted a link to the Bronco riding off of the Lion's Back trail a few months ago. (I searched but I could not find the link)

If I remember correctly, the dude drove up and down that more than once, to prove to his girlfriend that it was ok. She finally worked up enough nerve to drive the last time. Of course by then the brakes had heated up quite a bit from the repeated trips - combined with her riding the brakes the last time all contributed to the brake failure. If you watch the video - she did a fantastic job of keeping the truck on track, and it only actually fell off at the last section - which was somewhat close to the ground and impacting on (relatively) soft sand.
