Though not really mentioned in the article, it brought a thought to my mind.
A rather common thought among some preppers is that the farther away from people you are, the better off you will be. And I believed this thought had merit but now for my new thinking.
Longer term (1 year+), you need to be around other people so you have access to a large enough and diverse enough population so you can barter (or purchase) all the different items that you will need. By diverse, I mean people with different skills that produce a wide variety of trade goods and services. This is likely old news for most on this site.
