It depends on what side of North Carolina you are on. I'm on the Eastern side. East NC sauce is just vinegar & pepper. Yuck.
Western Carolina has tomato in the sauce....in the slaw, too. They have "red" slaw.
There is nothing nastier to me than pulled pork with vinegar on it.
In north Louisiana, we ate a lot of BBQ pork, too. Minced pork sandwiches...pork spare ribs....thick pork chops. Dang..I'm getting hungry thinking about it.
