2020 Jr Fair Barrow Show Announcement

During the February Senior Fairboard meeting, the Board unanimously made the decision to not offer market for market barrows at the 2020 fair in light of the current ractopamine controversy in the pork industry. Exhibitors will be responsible for the removal of the hog following the fair. Click here to download the letter about the 2020 Miami County Fair - Junior Fair Barrow Show.
