What the F?

I was surfing around the old interweb and found some interesting pics about dangerous roads. Basically it was a bunch of shots of roads on the sides of mountains with two way traffic, which should have only been one way.

This picture, however is not meant for driving on. Its for walking. Apparently its a tourist trail in China. So, there is probably hundreds of people who cross these boards and hang on to the chains for thier lives every year. Me? I think I would do it. Looks kinda fun.
