Hiding from the Apocalypse in the Countryside

I'm usually frugal, and apart from snapping up bargains during sales, I spend my time lurking in group chats and following the gossip. I never expected these two hobbies to accidentally help me stockpile supplies when the apocalypse came. Whether it's scorching heat or bitter cold, I have nothing to fear in the countryside. Someone wants to come rob me with a knife? I've had enough. I'll blow off both your legs and leave you to fend for yourself.
