Well, there is one in Texas, above Ft Worth. I have shipped some aircraft parts there.
There is one in Michigan where they used to build the “Saginaw 4 speed transmission”. All us old hot-rodders are aware of that one. IIRC, it is near Detroit.
I think that there is another one in the mid-west. OK, I looked it up, it is in Minnesota. Growing up, my friend’s grand parents were from that one. It is cold up there in the winter. They could not stop talking about the cold.
Now to read all of the replies to this thread’s question.
