After a full day of coaxing antique equipment through its paces, the threshers make their own evening entertainment.  Into sheds and the blacksmith shop musicians come singly or in groups.  Guitar, violin, banjo, Dobro, harmonica, and accordion gather.  Some sessions are formally scheduled but the most entertaining are the sessions just sort of evolve as various performers show up and take their turn leading the group.  It made for a perfect ending for the day for visitors as well.
