I think I've done this twice- but one of those times I was belayed by John P. I got up about 10'-12' off the ledge and got a decent piece. the problem occurred when John thought my request for "rope" meant 'tension' and sat on the lead line thinking I was going to pitch off. I called out "rope" again, John responded with more tension. Once more I begged for "rope", when John asked "slack?"- I said "yes, slack, yes, yes!!!". Shaking like a leaf, I pulled the line up to clip the piece. Suddenly all was right in the universe and I was not going to hit the ledge. I topped out without an issue...
What I don't recall was if we'd done a seperate line or did King Fissure. My recollection is Jim led this and I looked over at King Fissure and thought it looked way cool so we finished this and went back down and did King. Jim, Scott and I were climbing stuff that afternoon.
