I rent cranes for a living. A big part of my job is setting cell phone towers ( or any kind of tower for that matter). I watch guys climb em everyday like it's nothing. Most of the ones we set are in the 195' to 225' range. It 'bout makes me sick to watch the guys hanging from their lanyards and using both hands to work. If I had to I'd climb a tower, but I'd be like a cat with all my claws dug in tight. Aint no way I would let go with my hands not even if I had to pee!!
If I can remember I'll take some pics of a tower job and post 'em.
