We have PLCMC, the Public Library of Charlotte-Mecklenburg County. I pay an annual out-of-county user fee to access this system, which is really great. They get all the latest conservative nonfiction. The cities do not have their own, independent libraries.
However, several cities in Mecklenburg County have their own police departments, and there is a Mecklenburg County Sheriff’s Department. Some of their deputies are members of my church, and (at union rates) they do our traffic control on Sundays and act official at our annual festival ... even though we’re in the City of Mint Hill, which has its own police.
I don’t know why the Charlotte police claim the county. Maybe it’s historical, from before contiguous cities had their own police.
