I think everyone will always remember the moment and what they were doing when the first plane hit the world trade center. I was pretty young and in school when it happened. What a tragic day it was, especially for those in New York City.
It has been a long time coming but the 9/11 memorial museum has officially opened to the public today. Tickets can be bought online and there is even a free admission night on Tuesdays from 5pm to 8pm (its recommended to preorder those tickets as well).
I went to the memorial park last fall and really enjoyed what they have done with space, you can now even visit there virtually. I am waiting until the excitement dims down before I visit. What about you?
