Check out the video below of a decrepit crumbling cliff-side path in El Chorro, Spain. The guy who took the video must be suicidal because he's not even tied-in with a tether line. The Spanish government closed this path to the public in 2000 due to several tourist deaths but people still find a way to access it. Pay attention to the section between 1:20 and 1:35. That's just one of several similarly dangerous spots. This video would be great on an IMAX screen.
