Dickering duo Roland “Yummy” Raubeson and his son Mitch, from the History Channel’s new hit show “Down East Dickering,” tried their hand at something a little different on a recent summer Sunday: vending at the Lewiston Farmers’ Market. In an attempt to prove that Yummy’s assorted berry jams, known as “Yummy’s Yummies,” truly are worthy of the title “award winning,” Yummy and Mitch set up shop at the market as guest vendors for a day and offered taste tests of their jam to market goers. Those who could not get enough had the option of taking home a jar for a suggested donation. Of course, Yummy and Mitch also spent some time dickering with other vendors over some surprise goodies. How did they fare as market vendors? Tune in to the show next season to find out!
