Biggest I've ever been up is a mere 70' tv antenna tripod tower and even they sway a bit in the wind. Gets a bit unnerving sometimes. Especially when you lean back from the mast to fit an antenna with just your pole harness holding you.
But these guys are amazing climbing 1760 feet. They are not hooked on 100% of the time by the looks either. fook that!
Wonder what they had to fix.....................change the light bulb on top?
