States have no requirement for consistent pronunciation. A favorite of mine is near me and where I lived when I was very young. Des Plaines, Illinois is pronounced Dih Splaynz Illuhnoy. One s is pronounced s, one is pronounced z, and one isn't pronounced at all.
That's interesting. My English teacher and my geography teacher once had an argument over the correct pronunciation of "Des Moines"; we were covering the topics of American history and economy, respectively, at that time in those subjects. I guess "Des Plaines" is Spanish whereas "Des Moines" is French.
How was the Oktoberfest? I heard a Maß of beer costs about $13. 😨
Both cities' names derive from French, but the settlers took different approaches to pronunciation. There are many cities in IL and elsewhere that aren't pronounced the way you might expect. You would likely be amused to hear New Berlin pronounced new BUHRlun.
I did enjoy Oktoberfest, and the beers were that price. However I enjoyed my trip to Zugspitze and Mittenwald more as well as a day trip yesterday to Nuremberg. But now I'm on the plane for home.
