I'm not sure how well you can see this, but there is a particulary thin concrete bridge (in terms of depth and width) on the left here, I had to cross that to get to those stairs, no rail and a bloody old structure with about 6m drop or so below. That platform below you can see only starts at the other side of the bridge. Ahh! I almost curled up in a ball and cried.
I miss you Mexico.
