There are two communities named Rome in Wisconsin. One is an Adams county resort town with a population of around 2,500, and the other is a Jefferson County unincorporated town with a population of under 600. Neither Rome is in proximity to Green Bay. Hogan County, the location of Rome is fictional (there is no county named Hogan in any of the fifty states).
In the early stages of development the show was called Security Fences. As the crime aspect grew to become the center focus and Rome became less secure, producers decided that the show should be renamed Picket Fences.
