DES MOINES, Iowa -- Nealy 3,000 flags lined the lake front of Gray's Lake in remembrance of the lives lost during the September 11th attacks.
On Friday, the city placed 2,977 flags at the park. Spectators say the visual representation buts the magnitude of the attacks into perspective.
Greg Page's business partner lost a relative in the attacks. He remembers the day vividly.
"By the time I got to work, I was able to turn my TV on and see the second plane hitting the second tower. It pretty much threw everyone off the rest of the day, the rest of the year and even 15 years later."
Terrorists hijacked four commercial planes. Two of them smashed into New York's World Trade Center, a third slammed into the Pentagon and the last crashed in an empty field in Pennsylvania. The attack was the worst on US soil since Pearl Harbor.
For those who witnessed the attacks, the images will never be forgotten but for the generation born post - September 11th, they are just beginning to learn about its significance. On Sunday, Jody Lutterman took her 11 - year - old and 7 - year - old daughter to tribute to explain what happened that day.
"It is weird to explain," she said. "They will ask why would someone want to do something like that and you don’t really have an answer why."
Lutterman says she wants her kids to remember the unity Americans felt the day but she says that feeling is fading, "I think were loosing it in the last couple of years. It seems like people are less united."
It was a day that forever changed America and some feel the trust has yet to be restored.
"You wonder about what people are gonna do," says Cynthia Scott. "I’m afraid to travel outside of the United States. It's just a trust issue right now."
The Tribute Trail will be on display until Monday morning.
