Those workers have to climb to the top of a transmission tower that is 1,768 feet high. That's taller than the Sears Tower. The video starts off OK, kinda-sorta scary, but they're inside a somewhat-protective metal structure. And then they reach the top of that, and have to keep going up.
I have very little fear of heights, but this video is making me think, "Oh, hell no!"
And get the banal voiceover narration -- such as when the climber stops and looks around. "It's good to take a look around while you rest!" See, if I'm up there, I'm not taking in scenery. I'm focusing all of my energy on two things, and two things only: not falling, and not voiding my bowels into my pants.
And now, if you'll excuse me, I need to go sit in the corner and quiver for a while.
