June 7, 2004 -- Consider the undisclosed location disclosed. In the weeks after the 9/11 attacks, Vice President Dick Cheney hid out at "Site R," an underground bunker seven miles from Camp David, deep beneath Raven Rock Mountain on the Maryland-Pennsylvania border, says intelligence expert James Bamford in a new book due out tomorrow. In "A Pretext for War," Bamford describes Cheney's secure location as "a secret world of five buildings, each three stories tall, computer-filled caverns and a subterranean water reservoir," according to a review in the June 14 issue of Time magazine.
