I think you might of missed the intent of the last paragraph from the OP. I (and presumably Art) interpreted the wording as a post modern type of society where modern ammo was no longer available. These types of far fetched scenarios are not why I visit ETS...
I read what the OP wrote and then subverted it into a scenario my parents and grandparents actually experienced. There's a lot of valuable stuff we can learn from the Great Depression which may help in a possible upcoming long-term disasters.
