Yet another great question from a reader....
There is actually a wonderful scene in Bk 8 where Sookie on the floor in her pajamas gets out her old Louisiana state map and a pencil (so she can later erase the lines ) and draws out what she thinks are the vampire sheriff area boundaries ...
This is the scene :
In honor of the chilly night I pulled on my fleecy pajama bottoms, white with pink sheep, and a white Tshirt. I unearthed my map of Louisiana and found a pencil. I sketched in the areas I knew. I was piecing my knowledge together from bits of conversations that had taken place in my presence. Eric had Area Five. The queen had had Area One, which was New Orleans and vicinity. That mad e sense. But in between, there was a jumble. The finally deceased Gervaise had had the area including Baton Rouge, and that was where the queen had been living since Katrina damaged her New Orleans properties so heavily. So that should have been Area Two, due to its prominence. But it was called Area Four. Very lightly, I traced a line that I could erase, and would, after I'd looked at it for a bit.

his is my idea of how it might look
