Sarpy County Fairgrounds is the county fairground for Sarpy County, at 100 Main St in Springfield. Like most Nebraska fairgrounds it is owned by the county agricultural society and is in use well beyond fair week — rodeos, horse shows, tractor pulls, sales and community events. The 4-H side of the county fair is run by Nebraska Extension in Sarpy County, which handles entries, livestock identification and the certification a young person needs before showing an animal. The published address reads as a downtown one; worth checking against the map.
