That pic reminds me when I was 14 and the 'guys' in our group suggested skinny dipping at Casa Loma (a castle of sorts) in Toronto, so we being stupid 14 year old girls, said 'sure'.
So, we had to scale a rock fence of six feet, with a lot of help.
Then avoiding being seen. OK so far.
Then the guys took off all their clothes and went skinny dipping.
None of the girls did.
Ha ha, reality of life with good girls.
Just reminds me of that moment in time.
