Go read two books by Tom Clancy. "Sum of All Fears," which is about how some Palistenian (sp) group that blows up a nuke during a Super Bowl in Denver, there is also a movie for the book but is a little different with locations. The other book is: "Executive Orders" which is about a lot of things but one is a biological attack by terrorists in every major city in America using the Ebola Virus. The scarriest thing about it is the fact that it could really happen and Clancy put's that in perspective.
