Field Day of the Past is a family event sponsored by the Rockville-Centerville Steam and Gas Historical Association. This show mixes the warm, down-home atmosphere of the county fairs of yesteryear with exhibits and displays of museum quality. In the summer of 1992, a few steam and gas engine collectors gathered for an informal discussion on the possibility of hosting a steam and gas engine show in Goochland County, VA. They organized the Rockville-Centerville Steam and Gas Historical Association and hosted its first show, which attracted 5,000 people. Today the show has expanded into a 3 day event, held the third full weekend in September and draws a crowd of approximately 35,000 people annually.
