Fair office manager Shirley Embleton says the wild pigs spend the year on a 10-mile free-range property along the Marias River and about 30 are captured the Friday of the scheduled event.
But this year, fair officials were only able to locate one boar, despite flying the river. The event was postponed until Saturday, but neither the landowner nor fair officials could locate the absent pigs.
Embleton says next year, organizers will devise a new plan to locate and capture the animals earlier in the week.
