Love the freedom
I have been naked in a great number of places that are public. Mostly national and state park areas. I camped a great deal when my kids were young and it was common to strip off shorts when nobody was around. Lake Powell is probably my favorite place. One can hear a boat coming and either sit in the water or slip on shorts. In the early 70s, southwest Florida beaches were isolated enough to walk for miles nude. You could see anyone coming. One older man would fish the shore everyday and we became close enough friends I finally just didn't put my suit back on when I saw him coming. He seemed totally cool with it. Now it is all built up and you will get busted if you go nude.
Just posted a story of me being naked by a lake recently, at the end of a camping area, it's not CO but the one visitor I had was ok.
Also have other spots at non CO locations such a a river crossing in the bush where I like to get nude and relax when I'm in the area. Occasionally some hikers or campers stumble through but all have been OK with my nudity.
