Something I don't often see discussed in shtf scenarios, nor ever depicted in consumable media are enviromental toxins from decaying/damaged chemical infrastructure. I found a neat interactive map of areas in the us which are considered carnicogenicly contaminated from air pollution. A lot of the places listed are factories and plants. These are essentially no go/no grow zones if the grid was to go down or war break out. Some of these places may have huge storage inventories of highly toxic hazmat/hazwoper required response chemicals. These can seriously maim or kill you very eaisly/rapidly with minimal exposure.

Would be awesome if anyone could make an offline interactive version for download. Good to know what's around you were your at and also can help if you are looking for somewhere to move.

I would also like to find a map of all nuclear power plants and overlay it with wind direction map. In the event of a melt down you can reference whether you are in a danger zone. If anyone knows of one.
