What are the huge Cemetery Gates and Fence next to the Ticket booths in the lot across the street?

For the 13th Gate's 10 year Anniversary, Midnight Productions presents our all new haunted attraction:  Necropolis13!

 

Necropolis13 is a 40,000 sq ft haunted New Orleans style cemetery filled with dark crypts, underground catacombs (yes underground), and, more importantly, the living dead!
