Pitstops Along the Barbecue Highway is another excellent website on bbq in North Carolina and elsewhere. They even review a bbg restaurant in Austria. The reviews are a little dated, but aren't they all? Even this site is dated. That is one thing about a blog, you can get a feel for when the information was current.
The gem of this site is as complete (as possible) a list of bbq joints in North Carolina, sorted by city/town. Even though there are a couple of places not in the list, I am truly amazed at the work that went into compiling this list.
