In May I drove from Preuilly sur Claise to Paris to pick up Susan and her parents. Instead of using the advice most of the mapping websites give, I decided to avoid l'Aquitaine until it became silly to do so.
This took me from Preuilly to Loches, then Montrichard, joining the Autoroute at Blois. This was a new route for me, so I was totally unprepared for the sight which suddenly appears as you crest a rise at Montpoupon.
Honestly - sometimes it can just take your breath away, this driving in France lark.
