National September 11 Memorial comes to St. Louis

Driver Ron Smith puts the final cleaning touch on his trailer that has been transporting steel girders for the traveling National September 11 Memorial and Museum exhibition at Washington University in St. Louis on November 2, 2007. The 37-foot, eight thousand pound girders that visitors sign, are part of a display that will eventually be part of the 9-1-1 museum at Ground Zero in New York City. (UPI Photo/Bill Greenblatt)
