The way I see it working out is this:
There is the protagonist (or is he the protagonist?), who is a witty, smart, wealthy, and yet entirely insane survivalist who made a bundle of money and retired into a stereotypical bunker. Problem is he wasn't a survivalism out of really believing in the zombie holocaust, but because he wanted to have fun shooting guns, training in obscure skills, and planning defenses. Thus his guns aren't 'an assortment of guns to give your friends when SHTF', they are a massive gun collection. Oodles of tactical guns, MREs, gear.
There is the Judge, his wife and two children [a 17-year-old prodigy daughter with a high-gifted IQ 16-year-old typical teenage boy who is smart, but absolutely nothing too much next to Big Sister], and a random librarian/secretary type they picked up in the chaos. Their area gets caught in fallout from a nuclear exchange. [Shut up about the impossibility of an all-out nuclear war in the current political climate].
As for guns, the Judge (who is obviously a veteran too, because it's a pulp novel and I don't care for sanity) has obviously taught his wife and son gun safety and so forth (the son hunts), though Prodigy Daughter has avoided anything more than safety reasons because she just wasn't that much interested.
So they run. As some of you know, no doubt, in a serious nuclear exchange, most of the Eastern and central United States will end up spammed up with fallout in such heavy amounts that remaining there will not be viable. Because they are positioned on the southern side of the fallout cloud, they go South (most of Florida, Lousiana, Southern Texas and so forth is estimated to be relatively safe according to the maps I am using). But they can't stay there, because of the economic collapse and general violence and so forth, so they plan on crossing CONUS and going up the West coast into Canada and Alaska, where the fallout belts will serve to isolate them from the chaos and violence.
[Yes I know it is a questionable strategy. It's an excuse
Their strategy is composed of running and hiding from trouble whenever they can, rather than confronting it head-on. A reasonable one in the event of
