Texas and Kansas think BBQ sauce should be basically ketchup, but with even more sugar. North Carolina has great sauce with vinegar and spice. South Carolina's is also great with the mustard-based sauce.

It's pretty much vinegar with some spices. Years ago when I moved to NC, ordered BBQ pulled pork at a little hole in the wall place. Not what I expected. The pork itself was delicious but they poured that vinegar over the plate and essentially ruined it. I still get BBQ here, but order a side of rib sauce. That vinegar stuff is garbage.
