This is a little off topic, but the other day when i drove over to middlesboro i noticed something.
The sign heading into middlesboro with the city's population read....Middlesboughro or middlesborough or something like that.
I know the school and everybody else spells it like Middlesboro , but i was wondering how this came about, i obviously don't think it was a misspelling of the sign, but did it use to be spelled like that or something?
