Cycle paths in Northern Germany

Today's route went from Aabenraa in Denmark south into Germany, through Flensburg and ending in a small town called Hanerau-Hademarschen. We started early, which was good because I got a puncture in Flensburg and then went on a tour around the town to find a new inner tube.
Very grateful to the stranger who came down from his flat after seeing me trying to pump up the tyre with a mini hand pump, and offered his electric pump instead.
