<entity_1> is an annual Halloween event at <entity_2> amusement park in Sandusky, Ohio. Other Cedar Fair parks including Dorney Park, <entity_3>, and <entity_0> all have formerly used the <entity_1> name. <entity_2> is the only Cedar Fair park that still uses the <entity_1> name. <entity_1> debuted in <entity_4> and was only open for three weekends. Located underneath the Sky Ride on the Main Midway in front of Raptor is the <entity_2> Graveyard, also known as "The Land of the Lost Thrills", which was added to <entity_1> in 2004 and features tombstones of the park's rides that have been retired from the 1960s onwards. Cedar Fair, the park's owner, acquired Knott's Berry Farm—the first park with a Halloween Haunt—in <entity_4>, and implemented the event throughout the chain, starting with <entity_2>. For the 2011 <entity_1>, <entity_2> renamed two attractions due to protests. The outdoor attractions are run by the <entity_1>' Screamsters, a group of <entity_2> staff members who are commanded to scare visitors by The Overlord when night falls.
