The new Fox series "Alcatraz" has only been on the air for a week, but fans are apparently already going bonkers over the show. TMZ reports some are going on scheduled guided tours of the former prison that sits on an island in the middle of San Francisco Bay and searching for a secret high tech room that only exists in the TV drama.
A rep for the National Park Service says some fans have strayed into closed-off areas searching for a room that is described on the series as a "bat cave underneath Alcatraz." The National Park Service has now posted a sign that reads, "The TV Show 'Alcatraz' is fictional, many areas it depicts are not real. Closed areas protect you, historic structures and nesting birds."
