I’m thinking my European holiday when I was teenager – we drove through Belgium, Switzerland, Germany, down the Rhine to Italy then the Riviera back into France and back to Britain where we flew home. My sister and her husband rented an “RV” in London – it looked like a bread truck lol and so when we got to Europe, my brother in law had to drive on the “wrong” side. It made for some interesting drives – especially in Italy when we were camping on the top of a “mountain” and the roads wound around the mountain up!
