Visit in Basel

It had been very cosy to have a visit by Michi and Rolf while I had been in Habkern, so it came very natural that I would like to see them again. So in the spring of 2012 I went to Breitenbach myself to visit them again, which cannot be considered as anything but a success. While I was there I proposed Rolf that we should make a visit to Basel, which was the nearest city to Breitenbach, and what could then be more natural than beginning this visit on the town hall square of the city?
