Americans in Constance

What are americans doing in Constance, Germany? They might be here for a summer holiday, probably as usual, and a second look might reveal that they are not part in some way of a population who passes more or less incognito and discret like some german business men at the moment. The face mask is surely underpinning the noble reserve. It might just be the attitude that makes the difference, the guests seem to be less tormented by the impacts of the enduring corona crisis. From Afghanistan to Constance: this would be an absolutely stupid presumption to make people become ignorants, but what is there to do, maybe? If it is a kind of military operation it might be important to know that still employees of the US army are stationed in the state of Baden-Württemberg.
