having not read the book I guessed this was the case, as I don't think it was ever explained in the movie. Glad I was right.Kodiak said:Man... this shit is gonna start happening in Yellowstone, too. Which means the super volcano will likely go off shortly thereafter - thus the end of the world as we know it. ("The Road" was set in such a post-super volcano environment)
May Cthulhu spare you.
