It's in the romanian carpathians mountains: https://en.wikipedia.org/wiki/B%C3%A2lea_Lake
Thanks, reminded me of work in a French photographer's (Francis Annet) book that I have.
I trust you carried plenty of garlic around your neck! It works: I've never yet seen one, I think, though I did have to expel a bat two nights ago. I'd gone into the kitchen to take my goodnight pills (the door is kept closed) and this bat flew frantically around the room. As the windows were closed, I couldn't figure how the hell it got in. The only possible route is a ventilation tile on the outer face of the wall where the extractor fan is fitted. I wonder why it decided to crawl in through the very small apertures in that terracotta tile. Anyway, I had to open the windows wide for it to fly back out; I'd opened half of the window and it seemed not to know or understand, but continued buzzing me until I opened the other half too, and it flew away into the night.
I'm not afraid of bats, but I do know that they sometimes carry rabies, so best not take chances. Surprising, though, that it took the second half opened for its radar to be any use; I thought they could catch flies by radar. Maybe that's a naturalist's fantasy, just more filler stuff for those wildlife documentaries.
Now that I think about it, the same thing did occurr quite some time ago, but then I hadn't had the kitchen door closed, and it meant the damned thing was flying all over the apartment before exiting the french windows. My daughter was staying with me at the time; she was terrified. Probably because of the rabies, too. I don't really like having to do anything fast.
