Thanks, that's a great post from you. Not just because you complimented me, but it is obvious that you understand the circumstances well enough to really delve into the nuances of climbing on a daily basis. You took what I was trying to say in my post and really finished it off strong. This is a very demanding line of work and it takes it out of you. Just like the military, you need to have your wits about you or somebody could get hurt or worse. Thanks again. You always have great posts and I have repeatedly benefitted from your research and point of view.
