I admire the French for their directness. Both innkeepers and shopkeepers warn everyone not to leave anything in cars. Unfortunately (I don't know if it's the French or foreigners) thieves seem to be lurking, breaking into autos of unsuspecting tourists. This warning sign was pretty clever and to the point.
One of the quickest ways to make friends with locals is this; look for them circling parking lots, distinguishable by chic scarves or berets, start smiling with your parking pass held high waving it. They get the hint and zoom in, "Merci ! Merci!
Madame!" You've just saved them 3E. Passes are good for 24 hours and often after a few hours it's off to the next village for further adventure.
Europeans are more conscious of conserving water, energy etc. As we were leaving Bergheim Tuesday instead of it being wash day it was air out our bedding day. Window shutters wide open and bedding draped over flower boxes up and down the street.
