The climb up that smoke stack must have been a bitch, not for difficulty level but holding on to that little pipe would have broken my nerves every time a shake might reverb through it would suck so much I would have to wear brown pants if I wanted to climb it.
The photography and scenes are also very nice, I feel more awe for the scene itself than maybe experiencing any of the fear one might by being their yourself, I do find it classic that you always look like you are thinking: "Oh shit not again, let there just not be a gust of wind" then a slight breeze comes up and you might just need those brown pants.
Your right about that small pipe, basically a piece of conduit as it was not very strong. I did my best to never put much weight on that and used it more to maintain balance. I remember feeling very secure when I was on one of the lips but each time I moved up one was super dicey. The worst part about this photo is that this was actually after I already climbed to the top, I came back down and decided to stage this in action climbing photo. My camera was on a timer, I don't remember how long but I was rushing up to get position for the photo .
