It finally happened . . . after over 200 climbs one-sticking and rappelling, I finally got a rope stuck to the point I had to climb back up and retrieve it. I've come close a couple of times but this morning is actually the first time I had to re-climb the tree to retrieve my rappel line. Oh well, it was bound to happen sometime. I had broke off a dead limb I had climbed around as I rappelled down thinking it would help me on the rope retrieval. The rope fell ok but the retrieval string caught on the broken limb and I couldn't manage to pull it free and since the string was hooked to the rope it was holding it up in the tree. I just climbed back up, freed the pull down string and re-girth hitched the rope and got a second rappel in.
