Tangent story, I was in Manitowoc, WI, on a motorcycle trip. In WWII, they built submarines there, and they have a US submarine at a museum on the lake.

You might remember Manitowoc as being the area where Making A Murderer happened. Turns out that series only gives a light impression of the local accent there. The tour guide for that submarine sounded like he was speaking a completely different language from English.
