We're live from New York as the city prepares to remember a day none of us will ever forget.

Tonight, Mark gets a tour of the memorial at Ground Zero that will be unveiled this weekend.He'll also speak with a student who was in that Florida classroom with George W. Bush when the former president got word that America was under attack. Lazaro Dubrocq, now 17 years old, tells us how he remembers that day.

And we'll also hear from two men who were inside the twin towers when they were attacked.

Tune in tonight for a special edition of Connect at 8 p.m. ET on CBC NN.
