I've lived in Iowa all my life and I've never heard of it until now.
This was the first time a fair number of us had heard of that town. If the tv station map hadn't shown it we wouldn't have known of it at all.
According to
this site it was a small settlement from the mid 1800s until the turn of the 20th century, and that all that's left now is the bridge. I might have to go see if I can find this bridge.
