The first day of autumn according to my calender and is it equinox today, or not? In La Rochelle Sept 22nd had also been the day without cars for several years. We may have been the first town in the world to do this. People come into town by bus or bring out their bikes, their horses, their rollers etc. and it is choas. There will be even more chaos this year. The bus drivers have threatened to go on strike!
