Frankfort, Mich., is a small town on Lake Michigan at the base of the Leelanau Peninsula, less than a day trip from Sleeping Bear Dune National Park, Traverse City, ferries to South and North Manitou islands, etc. I have been there often and love it, but if you expected something different than what it turned out to be, of course you were disappointed.
Frankfurt, Germany, (pop. 731,095) is part of a huge metro region. My only experience there was s stop over in its airport.
Frankfort, Ind.? We played their high school team, the Hot Dogs, many years ago. Much different places.
As a now-Michigan guy, I am sorry, TJ, if you were disappointed in "our" state's version. I have many happy memories of the times I've spent there.
