The Fairgrounds have been a regional staple since 1949, when it was first used for a dairy show organized by World War II veterans who wanted to promote agriculture in the county, a Visit Prince William website states. It is the largest county fair in the Commonwealth, and it has consistently drawn more than 90,000 visitors in recent years.
Bridget Mullins with the Fair said attendees can visit the 4-H Club demonstrations or the livestock shows to delve into the Fair’s history.
