It doesnt look that bad, maybe If I got there, I would be scared, but its seems safe, so I would do it.
It doesn't look toooooooo bad. I'd probably be up for it if I see redundancy and can personally inspect the harnesses. What really scares me is hard core mountain biking. No way in hell i would do what these guys are doing <iframe width="425" height="349" src="https://www.youtube.com/embed/wAqt141eJAU" frameborder="0" allowfullscreen></iframe>
It's probably a lot more dangerous to drive 60mph on a two lane road, 6,000 lbs of steel closing together at 120mph, missing by only a couple of feet, being held on the road by about a square foot of rubber. But we do that every day.
They have something like this in Vegas at the Stratosphere except you jump off. It doesn't go very fast. I think bungee would be scarier.
