1. Got it, makes sense. How many times would this cut Wake?
It'd cut Wake into three pieces--though the portion in the Durham-Orange district would be pretty small. Alternatively you could cut Lee or something.
3. That's a good idea -- what do you mean by the High country here?
Basically the NW mountains--a bit of a nebulous region but basically centered in Watauga, Ashe, and Avery counties. Broader definitions include Mitchell and Alleghany and sometimes Yancey; there's a council of Government which covers all of the above plus Wilkes but I doubt Wilkes would usually be included.
5. How would that work? Isn't the 10th somewhat Charlottey here anyway?
Your 10th is a bit of a mix; certain portions of Catawba, Cleveland and Lincoln are somewhat Charlottey but the rest isn't. It's more that Mooresville, Gastonia, and Kannapolis are very much Charlotte suburbs and should be together rather than being drawn out into rural areas.
