On this 13th anniversary of the September 11th terror attacks, survivors are still vividly remembering and sharing their frightening stories.
"It's pretty much ingrained into my mind," said Evanston native Mark Shore, who was on the 62nd floor of one of the World Trade Center towers.
Shore attended a memorial ceremony at Firemen's Park in Evanston. He still wonders what happened to the people he saw that day.
"We saw the attacks. We saw the planes strike the tower. We knew immediately that our fellow firefighters from New York were going to go up and try to rescue as many people as they could, and we know the results," said Evanston Fire Chief Greg Klaiber.
At the Union League Club in Chicago, survivor Don Basco shared what was going through his mind during the chaos on the 57th floor of one of the towers. Basco, of Dyer, Indiana, was in Manhattan for business.
"I was scared and thinking 'I am going down with this building.'"
Dozens of memorial services are being held today in Chicago and the suburbs including Naperville, Homer Glen, Skokie, and Elgin.
