A Closer Look

In Rexburg, the Madison County Fair sits in the upper Snake River Valley of eastern Idaho, where potato farming, sugar beets, and grain crops stretch across a high volcanic plain flanked by the Teton Range to the east. Rexburg is home to Brigham Young University-Idaho, giving the area a distinctive community character blended with its deep agricultural roots.
