I was really disappointed to discover that the town of Neustadt an der Weinstraße, despite its lovely name, was not a pretty town at all! There were a couple of churches near the aire, which we went to have a look at and a bakery which I bought rolls, and then a Rewe, Lidl and Ali which I went to the latter of.
One look at the proposed route today convinced me that if we were to go on the Avenue Road at all, it would only be for a token distance. We still stayed on minor roads, mostly the Weinstraße, and stopped just outside Landau in die Pfalz for lunch and just outside Gaggenau for a cup of tea, passing through Karlsrühe en route. It was a lovely drive especially as we are on the edge of the Black Forest here.
I had planned for us to stay outside a hotel which let one park up for free if you had a meal there, but the car park was full and there didn't seem to be anywhere reserved for motor homes so we came back into town and have parked up in the municipal aire which is free and has services. It seems very nice.
