After a couple trips out, I was asked to clean the anchor after a sport climb. I was shown how to do it on the ground, but guess I was nervous. There's a small ledge at the top so, it seemed like a good spot to practice. I secure myself, took everything off and prepared for the rap down. Took myself off and did the double check, and realize that I have not threaded the rope through the rap hangers... Now I double check and even triple check BEFORE i take myself off or lean back on anything. Yikes.
