Golden Gate Bridge Anniversary
An exhibit of shoes in remembrance of people who have jumped from the Golden Gate Bridge is displayed during a commemoration of the bridge's 75th anniversary on Sunday, May 27, 2012, in San Francisco. The Bridge Rail Foundation, which advocates for a safety net along the span to prevent suicides, estimates approximately 1,558 people have died after jumping since the bridge opened.
