Rappelling was easing. You just jumped, kept track of your feet and hollered “yee haw’ as you bounced off of a wall or rock down to the ground, hoping to stick your “landing.”
Rock climbing was more difficult as you had to go UP. I had a bad back and thus was the world’s strangest rock climber. I didn’t do anything the way it should be done, but I managed to climb up the rock cliffs of Devil’s Lake in Wisconsin. I can remember getting to the top, panting, and just laying on the warm rock in the sun glorying in the physical exertion and accomplishment.
