Viewfinder: O'Fallon's Patriot Day Ceremony
The City of O'Fallon hosted a ceremony, remembrance walk and opportunities for volunteers to serve the community in honor of the 10th anniversary of 9/11.
Residents filled bleachers, clutching American flags and red and white carnations as they listened to guest speaker Dawn Robinson, who survived the attacks on the World Trade Center in New York City.
After the ceremony, attendees lined up to place flowers on the 9/11 memorial. Some signed up for the Remembrance Walk, while others headed inside City Hall to donate blood or help sort and box items for U.S. troops overseas.
