Today I walked in the pouring rain. But it doesn't matter, I don't mind walking in the rain and everything is better than yesterday's heat. Karl accompanied me to Läufelfingen and then took the train back. Not before another GPS lesson though. From Somerau on the path was quite nice, ups and downs through forrests and fields. A lot quieter and a lot prettier. Today's highlight was the old pass road "Unterer Hauenstein", the Romans already used it as a passageway between Augusta Raurica and the Mittelland. Not that I knew what that is, but it sounds old and important. Bernd, was ist Augusta Raurica?
