YOUR mystery??? I think it was my mystery, too.
I asked the question on the voyeurweb forum exactly one year ago tomorrow. Never got a satisfactory answer.

Yeah, I know. It's a fun little hobby trying to find out where stuff is. I don't spend a lot of time doing it, but if I have the time, as I did the other day, I'll make a go of it.
It was interesting how the three of us all contributed little pieces of the puzzle to get the mystery solved.
I read a few years ago that foreign tourist gawkers drove the locals away from Englischer Garten.
I've read that you don't need to ask where to find nude people at lakes in Germany because they are all over the place, particularly East German, though I don't think that is as true as it was 20 years ago (also from what I've read). Every time I asked on Voyeurweb where a particular German contribution was shot, the reply was always the same: you will find this at every lake all over the country.
As for the sandpits and quarries in Czech Republic, someone at VW has posted several contributions of pics he took of nude sunbathers and people swimming at what he called "the sandpit". He also said in the comment section that these types of areas are not uncommon in that country.
If you go nude at the beach where I come from, you will most likely be arrested for indecent exposure. Not even female toplessness is allowed.
