Someone else just visited JT and hung from climbing nuts and some webbing around a rock horn. If you think in those terms it might open up more possibilities. Doesn't take much in the way of gear , a few nuts, a few slings, a few carabiners. Knowing how to place them isn't hard either. Good luck camping out.
