This isn't the job for you: http://video.yahoo.com/network/101149635?v=8244494&l=5144241 Man, that would be intense.
I love heights. This guy does it without a harness, what a beast. If I had that job I'd like a harness just to know if something went wrong I wouldn't be screwed.
That would totally suck climbing down, otherwise I would love to be able to do something like that. I was nervous for the guy in the end. He should of locked on with his snap hook while fiddling with his locking carabiner.
scariest job i think overall is the people who have to shovel out debris from lock and dams... cleaning out the locks... knowing that you are in this tiny space that is surrounded by water
