I was primitive camping for the long weekend last summer in the Adirondacks. 5 of us total. We had gone swimming, not skinny dipping (not those kinds of friends), and I was out of the water on the other side of my tent where my friends couldn’t see from the waist down; I don’t care if they see but I respect their viewpoint on nudity. As you do when you change out of wet clothes you stand for a minute or two air drying while you line up the dry clothes you’ll be putting on. I had been standing there rummaging around naked for maybe a minute-ish and hear an engine noise - when I turn and look there’s a pontoon party boat with about 7 people on it not 50’ from shore that had motored along the shoreline without me hearing or seeing them…I think they booted the motor to let me know they were there. If they saw me, they saw all of me. I actually didn’t even flinch, I literally laughed out loud to myself.
