Plenty of great stuff even on an off year like last year does turn up. Anyone who goes consistently to shows knows that sometimes there are down times, but those of us who go regularly find our fair share of great stuff especially in the spring at Charlotte.
All you have to do is go back to old posts showing stuff at Charlotte to see plenty comes out there. Not to mention while in town there are some great places to visit like Gary's BBQ in China Grove among others.
