Continental Divide

We crossed the continental divide in France today, the rain that was falling to our right will end up in the North Sea, and the rain falling to our left will go to the Med. The idea of such a line has fascinated me since I was a kid, and I was bizarrely excited to cross this one today. Needless to say my excitement wasn't matched by any of my fellow travellers, even after a detailed explanation. Philistines.
