Doing stuff like that is the one thing I miss about being a industrial painter.
I worked for Eddy, a Cousin of mine painting for a couple of years. We painted Water Towers, Bridges etc...
On morning a friend of Ed's walked in and asked Ed if he knew anyone who would help him for the day changing some bulbs and doing maintenence on a Radio Tower...Ed told him that I was the only one he knew crazy enough to do it. As it worked out, I happened to have a new Climbing/Rappelling harness I had just bought in my car. I spent the day atop a 330 ft tower...While not nearly the height or the same level of "Pucker Factor" as this climb....I enjoyed it.
I did have dreams of falling several nights in a row afterwards.
At the top of the 330 ft tower I worked on, there was as much as 12" of sway with a 20 mph wind...can't imagine what the movement would be like atop a 1768 ft structure.
Also worth mentioning...the American Medical Association reports that a fall from a height of a mere 30 feet is lethal 95% of the time....Anything above that height becomes just a mental game...
If you do happen to fall from a substantial height.....just remember this ....One and Half front Somersault then lay it out in the Pike position. Go for points on form and difficulty cause your only going to get one chance at this dive.
