There were guards when a couple friends and I went to take pictures. Apparently they had just finished filming a Planet of the Apes sequel there and we just drove up to the gate and asked them if we could take pictures there. They said sure but not to go past a line not 20 feet into the park.
Long story short, we ended up befriending the guards and they gave us a once in a lifetime tour and showed us all around the park.
We got really lucky, maybe you can too.
RIGHT I live 3miles from this site the city of new Orleans had it slated for destruction in January of 2011. It was halted because the six flags and new Orleans joint venture on the old jazz land site used federal money. Until that writ is paid off, the site cannot be used for anything else. So at this point, the six flags is still standing. I will be providing new photos within the next week or so.
