As a part of my former "Life" as an instructor and rescue specialist I dealt with what we called "High Angle Rescue." One of my favorite moves was to anchor myself high, 300 to 400 feet off the ground, hook into the figure 8 or rescue rack on the back of my harness, and walk face down on the structure surface until I reached the victim. I'm scared of heights, but the adrenaline rush of that move or going head first with the rope between my feet took all fear away!
As far as that tower climb ... I'm so fat and out of shape that I can't begin to see the fun ... However, my tummy is churning.
