What are some good PostApoc generators and brainstorming aides?
There are lots of online generators for Swords & Sorcery worlds: you can find generators for dungeons, wandering monsters, settlements, treasures, races, terrain, coastlines, etc, but similar searches for post-apocalyptic generators turn up very little.
ETA: I realize this question is a little vague, but that's because I'm looking for any kind of PostApoc aides for general types of people, places, dangers and stuff. I also think this thread could be a good resource for others in the future.
Many games have "wandering encounter" tables and "random finds" tables ("Aftermath" has some great tables for scavenging in the ruins, for instance), but they're geared toward a single session or a single location; they don't scale well. This question is a system-agnostic attempt to find any existing aides (preferably online) for fleshing out large portions of a post-apocalyptic gameworld.
