I feel for them.
It’s all about route planning. Once we planned as much as possible but this was pre Google. We were in Brittany, our route took us through the village of Penestin. But we missed two things. There was now a bypass. And a very small notice, in French obviously, but not readable from a car. Saying not to go that way on market day. Well, it was market day!
Luckily they were packing up when two caravans tried to squeeze through. The locals were very friendly and understanding.
