That gargoyle shot scares the hell out of me: the lady either had nerves of steel or a death wish. I believe that during the construction period of many of those tall buildings, it was customary to hire a particular tribe of American Indians to do high work because they had no fear of heights, and were gifted with great balance. Maybe just a myth?
