Title: Six Flags New Orleans
Passage: Six Flags New Orleans (SFNO) is a 140-acre, abandoned theme park in New Orleans, Louisiana that has been closed since Hurricane Katrina struck the state in August 2005.  It is owned by the Industrial Development Board (IDB) of New Orleans.  Six Flags had leased the park from 2002 until 2009 when the lease was terminated during its bankruptcy proceedings.  The park is located in New Orleans East, off Interstate 10.  Despite various announced plans to redevelop the site, as of September 2017, it is still an abandoned amusement park in extremely poor condition.  The site is owned and maintained by IDB.  The site has 24-hour security and trespassers are prosecuted.  Videos and photos of the site have surfaced over the years from thrill-seekers.  This encouraged city officials to become more diligent in its approach to secure and ban tours of the park.  The park is no longer operational and safety is a concern.  Trespassing is prohibited, and the property is only visible from the highway.  The New Orleans Police Department officers can be seen patrolling the park daily to prevent trespassing.
