When I left my flat Saturday late morning, there were deviations and some smoke in the surrounding streets... Finally, there was nothing to worry about. The deviation was due to a large “vide grenier” sale and the smoke came from some sausage grilling. (I have a problem to translate the word “vide grenier”, which actually means emptying the attics, but different sources indicate “yard sale, car boot sale, bric-a-brac sale...”.) Anyhow, it was organised to allow the people in the neighbourhood to get rid of old stuff. The bus stop was closed.
It was an important one and was planned for the whole weekend. The ones selling Saturday would be replaced by others Sunday and the area covered by stands was large.
You could find almost anything ... and at very reasonable prices. I returned home with nothing except some photos.
Every hour there was a concert and some other musical entertainment.
As there are a number of bars and restaurants around, it was fairly easy to get restored. The weather was summer like.
