A few details about this picture intrigued me. Compare the size of the worker to the diameter of the discs. The use of white discs as markers ? . Each strand is at least 80 discs long, and maybe longer. And the hard hat. It would only be of help if he landed on his head, and what are the chances of that ? I don't consider myself to be scared of heights, but there is NOT enough money printed to get me to do that type of work.
