the Concours event has involved up to 500 cars of collector vintage (25 years old and older) bringing a season-opening festive flair to the Upper Muny Opera parking facility in Forest Park in St. Louis, on Easter Sunday. Crowds have been conservatively estimated between 10,000 to 20,000 as young and old enjoyed the vast array of automotive machinery from 1903 to cars that are a mere 25 years old. It's practically a community affair with informative commentary, displays, special food, chats with car owners, and educational "talks" that carry additional benefits for visitors.
