Two sisters were the winners of this year’s Mayville Winter Festival Medallion Treasure Hunt, an annual contest that leads up to the festival. Shauna Barber of Mayville and Tara Culbreth of Westfield located the medallion on Tuesday at Tom’s Point near Stow after a total of nine clues were posted on social media for the contest. Shauna and Tara received their prize — $100 each in ShopLocalCHQ gift cards — at Friday’s opening ceremony of the Mayville Winter Festival. The 38th annual festival continues through Sunday.
