ok wait.. im a newb..
did he really just use a bows arrow to support him?? and if so.. wouldnt he just swing into the wall opposite him?? looks awesome.. i just dont understand how its done.. people are f@#!ing crazy..
i suppose i would do it, if i knew it was completely safe, but then again... once your up there looking down, who knows.. your knees would start to shake, and your mind may never let you jump!! would have to be a thrill tho!
