What's behind the wall?

My Lincoln reference for today was sent to me by a friend who saw a CNN story about The Tunnel, a movie about the Atlantic Avenue Tunnel under New York City that supposedly contains hidden objects and secrets that would unravel many of the world's current mysteries. Some of these secrets include the missing pages from John Wilkes Booth, the assasination of Abraham Lincoln, and information on conspirators involved in Lincoln's death.

Of course there are rumoured to be other treasures like a perfectly preserved locomotive from the early 1800s, but what is that when there are Lincoln mysteries to uncover!

The filmmakers are raising money from the public to finish the shooting and excavation, so let's find out what's behind the wall!!
