On the second Sunday after Labor Day, some 200 antique and classic automobiles gleam across the Park grounds. Each year, the theme changes. The night before, the Preview Party offers a sneak peek at the cars, plus music, food, drinks, a silent auction, and an automotive art pavilion. All proceeds benefit Dayton History, a privately funded nonprofit organization, in its mission to inspire generations by connecting them with the unique people, places, and events that changed Dayton and the world.
