p. 335: Tour of the Mojave Wasteland "The Granny Gang" "Maud’s Muggers: This is a frightened city. Over these houses, over these streets hangs a pall of fear. Fear of a new kind of violence which is terrorizing the city. Yes, gangs of old ladies attacking defenseless fit young couriers. This occurs randomly, but there’s a high chance if it happening when you exit Cerulean Robotics." Fallout: New Vegas Official Game Guide Collector's Edition
