I had voted no for hiking in the nude. And geez the last time I seen someone nude in the stick: as a matter of fact the only time, was in the early 70's on the Verde near Beeline Highway. It was a gal topless romping in the river with a boy. I was floored.
I have worn shorts and got torn up. I slammed into beaver tails on side of canyon walls and had to cut my jeans to use my tweezers to pull the needles out. I was afraid of falling if I dropped my jeans and I did not relish the pain if I tried to pull the jean's leg up. I have had shirts ripped while hiking. Clothes is the extra protection.
However, in all fairness, depending on the mood, how the stars align, if I am all by myself, I have indulged in sunbathing on the rocks or partake in skinny dipping while hiking. Not often. The last time the urge hit me was when I hiked to Taylor's Cabin.
I was hoping to spend three days there and this was if I could find water. Well, by golly near the cabin was a large crystal clear, deep, shimmering pool of water. To make a long story short, I was hot, the day was warm, and the pool of water kept calling me, "come on in, come on in". So I did, in the buff and man did it feel great!
