Moss came over two Sunday's ago and we started working on this red oak we call The Leaner. He took out a lot of dead wood to prep the tree for my first climb. The wind picked up a lot and it got dark, but I was able to clip in and ascent 6 or 7 feet that first day. He came back last Sunday and we finished taking out some dead wood (got to practice some entry-level rigging) and then we started climbing. We guessed that his rope was set around 60 feet and the rope I went up on was set at around 50 feet. Due to the lean, we were hanging about 10 feet from the trunk when we started ascending. I learned a lot when watching Moss climb up and lanyard-in; it really helped clarify the things I've been reading. When it was my turn to clip in and climb, I had a better feeling of what had to be done.
