Anyone into this?? https://www.youtube.com/watch?v=Iuv__-nyO1M I haven't tried it YET, however, I am familiar with military style use of ropes - going down buildings, getting out of helicops etc, and would like to get involved into this. Question: where and how did you start this? Any way to learn it without having a mentor? Don't want to search the net, since I enjoy forum answers much more. Thanks!
