Today, the museum's special tenth anniversary display of September 11 artifacts will close. Hundreds of visitors have left comments with us over the past week or so. Below, you'll find a slideshow of 11 of these comment cards—from a firefighter, an Army wife, a visitor from England, and others who wanted to share their stories of September 11, 2001, and the ways in which their lives have changed since then.
