Ugh.... nightmare inducing! I follow some rooftoppers on instagram and every once in a while think maybe I should unfollow... but still - an amazing display of human spirit adrenaline and adventure!
Actually, these kind of photos bother me....because they will encourage other people to try stunts like this. Pretty much every year people die at the Grand Canyon National Park because they got to close to the edge trying to get a photo op. It's risk taking for its own sake. There are lots of good way to appreciate the mountains without doing something crazy.
