If you're anywhere near Lexington, NC or if you can road trip it, then don't miss the Lexington Barbecue Festival. It's been featured as one of the 10 best BBQ festivals in the south.
This one is not a contest. It's a hometown day with lots of food, crafts, and games for the kids. Be sure to look for the sand pig sculptures. Those are always neat.
For insider information, see my article on the festival at Yes You Can Grill. One tip I'll toss out is to arrive early. This festival gets bigger every year, and the crowds are huge starting about lunch time.
The official page is also chock full of information on this great southern fun fest.
