Also, I'm interested in seeing just how closely these tunnels connect to cities with KNOWN terrorist groups/cells.

Terrorist Cells Too Close For Comfort (Just over the border in Canada) The Washington Times ^ | December 10, 2003 | Jerry Seper- Posted on 12/09/2003 10:23:51 PM PST by quidnunc- Buffalo, N.Y. – They're hiding in plain sight, just north of here — a short striking distance away from some of America's most-vulnerable targets. - This silent army of terrorists, including members of al Qaeda, has the "capability and conviction" to support devastating attacks across North America, operating out of "sleeper cells" from Montreal to Vancouver, according to U.S. and Canadian law-enforcement authorities. - Attorney General John Ashcroft has called the 4,121-mile U.S.-Canada border a "soft spot" for terrorism, and law-enforcement authorities in both countries think that cell members in Canada — and others who have relocated to the United States — are awaiting orders, financing and a window of opportunity to strike again.

Okay. We know Montreal has a network of underground tunnels and passageways, complete with map posted on internet. good grief.

NYC-vast network of tunnels, same for NJ. Same thing for Chicago, same for Detroit. I'm going to check out Indiana and Ohio, next.
