The world's biggest corn maze, in Dixon, Calif., is a popular tourist attraction for some and a frustrating exercise that ends with a call to 911 for others. The maze, which covers 63 acres (about 25 hectares) has been certified the world’s largest by the Guinness Book of World Records. Matt Cooley, one of the operators of the maze, says the average time to get through the maze is about two hours and most of the people calling 911 have often been in there around four hours or more.
