I found another book devoted to Q-joints in North Carolina:
"Kent's Carolina Barbecue Book: Carolina barbecue restaurant reviews, recipes, history, culture, more" By H. Kent Craig.
You probably recognize Kent as he had a GREAT website devoted to NC Q-joints for about 11 years. He has rolled that website into a book and it is really interesting and good. I don't totally agree with ALL of his reviews, but that is just a matter of taste and opinion. That is exactly why I am doing my own research and quest to find the best barbecue in North Carolina!
