Incidentally, the North Carolina - South Carolina border is in the middle of being clarified. Here's a story about it. The full story has several other problems the clarification is causing.
Here's the doctor's home. The blue line is where South Carolina thought the border was, the orange line is where North Carolina thought the border was, and the yellow line is where the boundary commission has determined where the border is.
In other places the border is moving to put people who thought they were in South Carolina into North Carolina, including a convenience store that sells fireworks and beer that it won't be able to in North Carolina. (South Carolina has the most liberal fireworks laws in the US, and the store would be in a dry county in North Carolina. The store is located on the border mainly to sell beer to thirsty North Carolinians and some 70% of its sales are in those two items that would be banned once the clarification is approved.
