We remember and honor all those who lost their lives or were injured on, or because of, 9-11-01. We also honor all their loved ones who were left behind, and all the first responders. We will not forget your sacrifice.
During August of 2001 we visited Ellis Island and the Statue of Liberty and took a picture of the World Trade Center Twin Towers. Little did we know that less than a month later the towers would be gone. The picture is the only one we have, rather hazy, but here it is. Many of those who were killed were there at work on that day.
Edited to add: We visited the same places a week ago and here is how it looks now, from about the same place. You can try matching up the buildings and see what is new, if you like.
