The coastline

 There was this random fence that blocked nothing and was only one row. Maybe it was supposed prevent people like me from walking close the edge...

...like this.

I was very careful in how close to the edge I got. Who knows when the edge will give way again. I would have to walk very far along the coast to find a place I could even possibly climb up, and that would be with no injuries. So, if you do this please please please be very careful where you step!
