No grocery stores, no clothes or tools or running water. Suddenly we're back to Genesis but with our human nature unchanged. Would your local community have what it takes to survive?

Hell no. Most of what would get disabled is useless entertainment crap. But I have in my shop several Faraday storage containers for the stuff that matters. If you know how to protect an entire modern vehicle let me know. Meanwhile I'm buying a pre 80 truck without any electronics.
