It rained. All night (there was even a rather splendid thunderstorm) and all day. So although in theory today's drive was only a little over 2 hours, in practice it took a lot longer.
First stop was at a supermarket to stock up, and then later we stopped for lunch and then, briefly, for me to buy some money. We found the aire here at the second time of asking. It is supposed to have services, but we can't see any. However, it is definitely the right place. And tomorrow to Oberstdorf!
