In aptly named Pickens, South Carolina, the guys scour the sprawling inventory of a father-and-son picking duo. They uncover plenty of rare and unusual items... But can they make a deal with the two pro collectors? Next, the guys meet Mary who has inherited a 300-acre property, home to a huge untouched collection. After warming up with a few impulse purchases, Mike and Frank get serious. Plus, while trying to convince the guys to take her on the road, Danielle leads them to an inconspicuous cement factory. It's the "Holy Grail" of picking -- Gordon's collection includes a jam-packed vintage general store, and building after building of unbelievable retro treasures.
