I could never do that....without a safety tether...i mean the climbing is not complex, but damn, if you fell it would be certain death.
The guy that posted this has been trying to take it down. His company is worried that people will be afraid of the safety issues involved. But I
don't really think that is the point of this video. It is just quite impressive that people have the balls to do that kind of work. (of course it
seems pretty silly to do all the climbing, just to replace a light bulb or something....should just use some fancy fiber optics or something creative)
