We'll be headed south from Pennsylvania in a couple of weeks and would love to hear of any chowhound destinations off I81 in VA, I77 from VA to Columbia, SC, and Rt. 301 through GA to Rt. 84 over to I75 down to Gainesville. Any fare is game, though we do love BBQ, fried chicken, and hushpuppies. We eat from one end of the spectrum to the other. Any suggestions?
