Road trip northwards coming up in the Fall. Any can't-miss places along this route? North of Asheville through Johnson City, TN to Bristol. . . Looking especially for great BBQ, Southern/Soul Food and Diners/Greasy Spoons/Burger Joints, although more high-end spots are of interest, too, if they're really exceptional. Oh, and remarkable sweets of any variety! Have heard some talk about a burger place famous for being Hank Williams' last meal, anybody know more? Thanks in advance, 'Hounders!
