And a few places like Virginia, you have Cities and Counties, and you can only be in one or the other. Sort of a Vatican City/Italy situation, except the same country.
I omitted it for simplicity, but San Francisco is basically that: a consolidated City and County, the only one in the State. I mean in legal effect it washes out to a charter county that is also called a city, we have a Board of Supervisors and a Mayor but no city council, and we employ both a Police Department and a Sheriffs Department.
Texan cities though, some of those cross into three counties.
