Every year around Halloween, Knott's Berry Farm, a theme park in Buena Park, California, transforms into Knott's Scary Farm, their month-long Halloween event. The park is filled with over 1,000 monsters, thrilling mazes and 'scare zones'. The city buses in Buena Park also take part in this transformation. This time into a rolling, rusty and wrecked zombie machine.
