LoveThesePics.com posted a photo gallery about a Tour of the abandoned Fix Flags amusement park in New Orleans. Very creepy photos, and very post-apocalyptic. Absolutely reminds me of Wasteland or Fallout. The park could easily be the HQ of the Killer Clowns, which is probably a staple of Postapocalyptica.
The site seems to have some pretty cool photo galleries in general… awesome for inspiration.
