There was a rope left in the Vail Amphitheater that I retrieved on Saturday 4/9. It was left tied off to a tree/bush to the right of the Fang, running down the descent. I'm not sure if this was for an emergency, but if it wasn't, I can't see how a fixed line is needed for the mellow approach and descent. On a side note, it did leave the tree/bush broken at the base; let's try to respect it up there :)
Fire me a description of the rope and what was tied to it and I'll arrange to get it back to you!
