17 years ago today, our world changed forever. 9-11 is one of those rare occasions that remains burned in our memory, making it possible to remember that day as if it were yesterday.

Since September 11, 2001, I've seen a number of tribute videos that bring tears to your eyes. The one posted below gave me chills. I had never seen it before today. It's the most moving 9-11 tribute video I've ever watched. Take a moment today and give it a watch.
