Seems like it's unique to Detroit. I've tried for thirty years to get software companies to extend their road trips to Detroit. But I get told there's only 670,000 people there and that's way too small. Then I inform them there's 4.5-5 million people in the Detroit metro area. So now this is the reverse, instead of saying North of Detroit they tar and feather Detroit in the story.

One of the Doctors mentioned is in Ada which is near Grand Rapids and clear across the state!

I went to West Bloomfield high and lived in the area for while. And agree with you.
