I've gone to Knoxville in the spring each year for the last 10 years or so for the F100 Supernationals truck show, but I haven't really found much at all in the way of card shops. There is one on the way to Pigeon Forge in Sevierville, but they didn't have much at all, and its mostly football (Peyton Manning in UT garb rules!). Wish I could offer more help, there is one more shop that I stopped in on the main drag that parallels I-40, but I can't remember the street name. Not a bad shop, just mostly football and high wax prices from what I remember. LOL, if you have any better luck, drop me a line so I can check it out when I go back in May.
