I’m on a bridge consisting of three thin metal wires in a V-shape, one for your feet and two for your hands. I am balancing precariously as the single line for my feet keeps moving side to side with every step I take. Right below me a is the river, the water cascading over dark grey cliffs that would surely kill me if I fell. I would be scared if it wasn’t for the double safety rope that goes from a fourth wire down to my harness.
