Hi David, welcome over here!
Can you tell us more about the novels you wrote? I think it is always interesting to see fleshed out ideas of how a potential collapse could look like.
I agree with your philosophy. If we are going to face a sudden collapse its just about making it through the first couple of months and then most things will be dependent on our surroundings (unless you have a hidden underground shelter with many years of food of course).
