I was just there a month ago. It's still a very somber place for sure. They have cleared both foundations of debris and are working on building the memorial site. Right now they have the plans laid out and the names of everyone killed on 9/11 and also in the bombings that occured there in the mid 90's. They are still in the process of tearing down two surrounding buildings that were damaged when the towers fell. They are being taken down floor by floor so as not to disturb any surrounding structure. Also WTC #7 which fell on 9/11 along with the towers is completely rebuilt and functional. I was actually fortunate enough to go inside of WTC #7 and see the view in to the two towers foundations.

Still to this day the whole thing brought back those terrible memories of that day and makes you re-live it as vividly as when it happened.
