Roasting Ears of Corn Festival Pennsylvania's oldest Native American festival is held annually in August.  For more than 35 years this festival has spotlighted American Indian dancers, musicians, performers, fine artisans, and craft vendors from throughout the United States and Canada. The event also includes  life-ways demonstrators such as flintknapping, primitive cooking techniques, and tipi and fur trade encampments. Each year’s festival is a unique experience for people of all ages.
