You might check w/ pork producers ... Pick TN Products at http://www.agriculture.state.tn.us/Ma... lists several. Note that this link defaults to East TN but the buttons at the top will take you to Mid TN if you want to travel that far.
Swaggerty's is just north of Pigeon Forge and is still a 'small town' shop and might be easily approached. I know some neighbors of mine sell beef at farmer's markets and they have to go to an approved kill place up in your direction. That might also be worth searching out.
