Six Flags America Amusement Park

Six Flags America is a theme park and waterpark located in the Woodmore CDP of Prince George's County, Maryland, near Upper Marlboro, adjacent to the Washington, DC metropolitan area.

Founded as a wildlife center in 1973 by Ross Perot, ABC television operated the park as a drive-through safari called The Largo Wildlife Preserve, from 1974 until its closure, in 1978. The property was bought by Jim Fowler's Wild Kingdom; thereafter, the site was gradually converted from a wildlife preserve into a theme park named Wild World. In 1992, the park was renamed “The Great Escape: Adventure World” after being acquired by Premier Parks, before being edited again to “Adventure World: The Thrill Park”.
