In a worst case scenario I would still rather be where I am with our survival plan, our friends relatives and contacts(hunters, carpenters, farmers, welders etc.) than be in a foreign country where I know no-one.
We live in the country, have access to a woodlot for firewood, have a natural well for water, grow our own food and have a back-up generator for electricity. Why would I want to leave.
Now if I lived in a large city on the coast in an apartment I might consider moving, but that is a personal choice and an individual will have to determine what their gut tells them.
