Like others, I have been thinking about it. I do have a short supply of canned food always stored, but nowhere near what you would consider being prepared.
I will probably buy a bucket of emergency food online to last a few months, in case the zombie apocalypse hits. I do have a small propane stove, a good supply of lighting options, including batteries, flashlights, oil lamp.
I don't have a backup for water, I guess i'm hoping it wouldn't get turned off.
Sometimes I wonder the amount of chaos churned from a serious disruption of services. I'm pretty sure society would turn into a jungle. It is well knows that nearly half Americans don't even have a few bucks saved for emergencies, so you can be sure they are zero prepared in any other way.
Looting and rioting would soon follow especially in cities where people are piled up and heavily depend on supply chains.
