Darn, I live within a tankful of the biggest city in the country and have a state forest next to me which has a lake (only about 1/10th mile away).
I’m toast.
Oh, no! It sounds like I wrote that scenario based on where YOU live. If there are riots over the outcome of the election, you are probably okay as I don't think those will last long enough for zombies to head out of town - food and water will still be available if those riots stop after a week or so if they last that long. I hope you are a prepper so you have what you need.
If the economy collapses and food and water go away, you need a plan A and B. Do you have family or friends farther away from the city so there is some safety there? You would need to leave as quickly as possible if you see the economy is failing. People will be bailing out of that city, millions of them.
Perhaps you have thought on this and already know what you will do - I hope so. Stay safe.
