Good points, Andy.
I guess it all depends on what your assessment of the threats your region is susceptible to. I've heard some people say that living in a city is almost completely "artificial", with all of our needs being magically delivered to a faucet, furnace, or grocery shelf on a reliable basis. As people lose their knowledge/ability to perform those once necessary tasks, they are more reliant on someone else to provide them.

Good luck and thanks for the reality check.
