Yale Bologna Festival in Yale
The Yale Bologna Festival is an annual festival in Yale, Michigan, a small St. Clair County city of roughly 1,900 residents that bills itself, per its own Wikipedia entry, as the unofficial Bologna Capital of the World, largely because of this festival, which began in 1989. Yale bologna is sold in area grocery stores year-round. Specific current-year dates, organizer details, and a full activities schedule could not be independently confirmed beyond this core founding history at the time of research.
Its unusual sausage theme makes it a classic Michigan weird-food row.
