On November 15, 2015 Théo Sanson walked nearly 500 meters on a slackline rigged from The Rectory to Castleton Tower in Castle Valley, Utah.
I envy people like this, both their youth and access to enough money to do their thing.
The question is always, "Why?"
The answer is, "Because I can."
"Have you conquered anything?"
"Only my fear."
I doubt you would see something such as this in any sub-human land. Mohammedans could not even think of doing anything not directly under the power of their allah.
Meters? however far that is, it's a long way. I get vertigo just watching the video. I remember the maniac going between the Twin Towers. Terrifying.
