Ummm...
You seem to have your facts wrong... the entire city limits of Charlotte does straddle both states. So you might want to one visit Charlotte, like I have dozens of times and lived in the area, or two look at a map sometime.
Might want to do more research before spouting off trying to correct someone who has actually visited and lived in that area.
I live in Charlotte. About 11 miles due south of the city center - and about 4 miles north of the border with South Carolina.
The RNC is being held “uptown”, which, as I said, is quite a ways from South Carolina. You said the protesters would just need to “run across the border” to avoid the NC National Guard. I merely pointed out that those protesters would have to run a half-marathon to reach the border. Those soy-boys and granola-girls would be out of breath, and out of options, before they reached Dilworth, let alone SC.
