Cool - do you remember where you got them? Would love to see a State by State version of that... In Florida we could also have the ‘spades’ section be toxic plants ( what NOT to eat) - we have a lot of those...
There is a show on Outdoor Channel called Best Defense: Survival. They have a lot of good advice, I recommend it for people that are concerned about the SHTF scenarios.
They broke it down into a few situations but they recommended that you store enough food/water for a 90 day situation, because somewhere between 7 to 90 days is the most likely scenario.
