@sailingmusic I don't think I even noticed the lack of litter while there but you are the second person to point that out in photos. Alleyways here would be a mess of broken glass, cigarette butts, etc.
We were in Austria a few months back. The things that really stood out to me were, no litter and no dog dirt. I also noticed how quiet it was, because at home there is always noise of some description, especially background traffic. Lovely shot here, looks an idyllic place.
