Just a quick observation from a month long trip to many places this summer:
By a mile there were more Americans, and more English speakers, in Munich than any other city I visited. Nor was it even close!
Both a lot of tourists (of which I was one, aka not in traffic but are traffic), and a lot of expats. Both obvious Americans (the type where you basically just know from seeing them), and many as well who I assumed were German until they opened their mouths.
Hmmmm. I wonder why so many of us Americans were in Munich? Or maybe the copious beer just makes us open our mouths and talk so that we can be more easily recognized.
