Holy Frijoles!!! I have terrible acrophobia and watching the video almost made me faint...
the guy doing the video states that it is unedited..he was going at a pretty fast clip...
here is some info on the place

I am not good with heights..and boy does that make you feel something in the pit of your stomach.
Do you remember the scene with Tom Cruise on the face of a cliff..that supposedly was for real and not in front of a green screen...or is it blue screen..anyway..not fake.
I would love to see him do that Spanish Walk ;-)
