Do you remember your first visit to a museum? You may have uncovered a passion for geology as a student on a field trip. Or realized you wanted to be a pilot while gazing up at the Spirit of St. Louis. Or maybe you started visiting museums with your children, and watched as they touched a rock from the moon or stared wide-eyed at a Tyrannosaurus Rex fossil.

Every year, millions of visitors pass through the doors of America's history, science and art museums. One of the principal goals of these institutions is to create lifelong memories of discovery for visitors.

Museums are an integral part of culture. What is your favorite museum story, memory or exhibit?
