Oh, it’ll be mighty dangerous for a spell, that’s for sure. Our urban ghettoes might totally implode, thus the demand/need for martial law.
But in the suburbs, black markets will spring up like mushrooms to fill the need as a stopgap, until market resupply chains are reestablished. That could last for days to months.
That’s why I think knowing how to fix things, knowing how to make it work, will be the most important. knowing what to eat, hell, when I was a kid we used to eat dandelions alot, very nutritious, they grow like weeds, you know what I mean.
But for every one like you and me who have fishing gear stowed, there’s a couple thousand zombies ready to eat brains... it ain’t pretty at all!
