I fell off that cliff about 8 years ago, just a few meters past where he is riding. Luckily it was only about 10 meters, and I had a full face on, and full body armor. Still walked away with a separated shoulder, and some major bruises. After that, I learned to always pack a Red Bull or something with caffeine when I don't make coffee camping. Foggy brain = crashy body...
My buddy had a similar fall there and landed on a ledge about 8-9' down as we all watched, he was lucky and we were spooked! Dang kid hadn't slept at all the night prior.......dang video games! That's my home turf!
