I don't blame the city for wanting Six Flags to reopen SFNO, but SF has enough trouble operating the parks they do have opened, so I don't blame them for stalling either. If I were New Orleans, I wouldn't waste a lot of time in court. I would terminate the lease and start looking around for other suitable options to get the park reopened. Go for ownership of the assets (if they are worth anything) currently in the park as part of a "payment", and use them as a morsel to entice another company to reopen.
Talk to the guys behind Freestyle. If the Myrtle Beach venture is a success, then the former Jazzland could be the next project, and it too could be had for dirt cheap. New Orleans is a funky kind of city that Jazzland could derive much influence from....even more than it had before.

There are links to Google Earth photos in the comments below the story. If anyone thinks all they need is a little oil and bolt tightening to get it working again, look at those photos.
I think they should reopen though its not the economy for it! WHy not? They might be able to improve it!
