cliffs of karst, china

I'm not a climber.  I once climbed, but that was enough.  It may have something to do with the fact that my friend took me on a 5.9 multi pitch climb my first time.  Since then I have a new appreciation for heights and people that climb.  Couple climbing with National Geographic and good photographers and it's usually a good combo.  Case in point; this recent video clip from China is pretty incredible and worth your time.  https://www.youtube.com/watch?v=AIO2MEJCD9k
