Yes, you will have to get with your tribe in a safe location. Two I have identified as "relatively" safe are southern Chile/Argentina - Patagonia, and the islands off of Juneau, Alaska. Neither are ideal for a number of reasons, but 50 talented, like-minded families coming together like a Mennonite community working together at either of these general locations might, with a lot of struggle, make it work. Or not... Is the best we can hope for Ragnarok?
