Earlier this week my cousin Brad invited me to go climbing and rappelling with him and some friends at Devil's Lake. My experience in the tree business has gotten me comfortable hanging on a rope and swinging through the air. But it took me a little bit to get comfortable in the rappelling setting. All the principles and even techniques are similar, if not the same. But with the trees, so often you have branches to hang onto and even stand on. Today, the context was a little different - just a face of rock to push against, and certainly nothing to stand on.
Nevertheless, my first rappel was safe and controlled. The second one was a lot faster - I had the figure-8 hot from friction when I got to the bottom.
