Since we're talking fish here...
I grew up in a little town called Archbold, Ohio. My Great Great Grandfather was the first mayor.
Back in the 1800's the creek overflowed and when it receded the town was covered in Carp. So, all the neighboring towns called Archbold 'Carptown'.
Now they have an annual festival called Carp Fest each summer.
Here's our mascot: Cornelious Carp
