As a kid growing up in Green Bay, WI, I could always tell when the stations hired voiceover guys from Chicago to do their station IDs because all the stations had secondary transmitters in the Upper Peninsula. The Chicago guys invariably told us those were located in MariOnette, MI.
Shelwood, when I was growing up in the Upper Peninsula one of our favorite games to play was "take a drink whenever the voiceover guy pronounces the name of a city incorrectly." Marinette, Ontonagon, Sault Ste. Marie, Baraga, Escanaba, etc.
The best was when they obviously tried to sound it out before saying it on the tv news. :)
