One would have to be an adrenalin junky to take that path. It appears to be crumbling beneath his feet. One time I attempted to take the mule ride into the Grand Canyon. One quarter of the way down I jumped off after the mule's hoofs kept stumbling near the edge of the narrow path. I refused to get back on and the mule had to continue on since they are trained to follow one another. I was so much happier on my own two feet and completed the journey to the bottom and back up to the rim.
One of my reoccurring dreams is being caught on a little ledge with no way off. This video has reawakened the fear of heights in me, now I need therapy.
