I rode a few wall-climbers in my day, one on a 140 ft. radio tower...30 mph straight winds left me with one arm to work with (wall-climbers aren't attached to anything but a quarter-inch steel cable)...I don't mind heights, but unstable footing, whether it's a foot or a hundred feet up, renders me helpless...Ask me some day about the 32' swayback extension ladder I
used to own...
