The kind people along the route will always be first that come to mind. Some fresh water for the bidons, encouragment for the endeavour, ….
But also the strange french things like “no card under €5” or “this camping only accepts cheques”, shops that close for 1,5 hr during the day. 
What was also striking was the changing of the language. Around paris I understand everybody more or less. Once past the auvergne it’s very hard to understand anyone. 
I will sure remember the many good croissants, baguettes and coffees. 
Many thanks for whoever put time and sweat into this long route. 
Merci!!
