Showcasing cars from across the country and through the ages, the Grand Prix is the only such event in the world to be held in a park. Cars race through the curvy 2.3-mile circuit in classes determined by age and engine size. In the course of its 19-year history, the Grand Prix has raised more than $1.3 million for the Autism Society and the Allegheny Valley School.
