The guys who climbed the Bridge to Russky Island were crazy enough. These climbing Russians, however, might just one-up them in batsh*t craziness. Their whole skywalking schtick is climbing a steel tower and doing acrobatic stunts while dangling hundreds of feet in the air from a beam. NO THANKS. Again, prepare for your hands to start sweating within the first minute. As to why they do this? I haven't a f*cking clue.
