Forage into a Strange World

"Forage" is probably the wrong word to use. As usual. Maybe I should buy a thesaurus. Or I could use one online.

SO! I was thinking of making this a place to put my most random thought processes. And perhaps when I get to a point where I'm not in close contact with people I know in different states and whatever, actual updates on life.

My most recent random thought process has been about a post-apocalyptic world.
When trying to create one it raises many questions:

What destroyed the world?
How did the survivors survive?
What do they do to continue life?
Where do they live?
Are there any new creatures that arised from the aftermath of the apocalypse?
Are they dangerous to the survivors?
Are there different factions of survivors?
Or did they all end up together?
What is used for currency?
Or is there no currency? Did they revert to a bartering society?
What do they eat?
What kind of crops can be grown in the soil?
Are there new plants?
Has technology advanced or reverted?

All this came from the fact that there has been one chick staring down the barrel of her gun at me for a very long time. Her gun looked rather modern. I figured she'd hold her own in a post-apocalyptic world. She didn't fit in any other world I've found. And she's killed whatever has been behind me so cooly I didn't really want to meet her. But she finally introduced herself. Still don't know her name, but she's rebuffing advances left and right, apparently. She probably doesn't tell many people her name.
Thinking about all this makes me want to play Fallout. Which is one of the only complicated-looking games I've ever had the desire to play.
That chick would fit well into a world like that.
