I just had a brainwave, which is not very often as my brain is not always tuned in. Yes, we once had sand in our local market town of Solothurn. They decided to stage a beach volley tournament on one of our main places, and I happened to be there, with my camera of course, when it was being prepared. I do not know the if the sand originated in the desert. It was probably dragged from one of our river banks or lake shores – who knows.
