off the beaten path from Asheville to Charlotte we researched best rated Carolina BBQ - Hubba Hubba Smokehouse did not disappoint. Cash only fyi.
Also - if you have some extra time - check out the Cowpens Revolutionary War battlefield in Gaffney, South Carolina (not far from Charlotte NC). Grab a map from the visitors center. We took the hour+ car tour and listened to the narration for each stop from the website on our phone. Very interesting!!!
