Fully understand the desire to not stick around for what comes after but I think its important to remember nearly all post-apocalyptic media is made for pure fantasy enjoyment. As long as a few people survive they will almost certainly band together, humans much prefer working together over the lone wolf bullshit you see youtube preppers going on about for shit hits the fan scenarios. As long as the radiation didn't do a number on you I think it would actually be a much better time to be alive than now tbh, back to small communities working together with common goals and work that actually has a direct material effect on your well-being and those around you..... man I wish I lived in a county where land wasn't insanely expensive and planning permission wasn't a bastard, I'd happily go and live like that now.
