If you haven't already, you should subscribe to Canadian Prepper on Youtube. Go ahead, I'll wait. Every week he makes several high-quality videos covering all aspects of preparedness, especially physical and mental preparedness. Plus some gear reviews.
In this video he talks about the pros and cons of being an urban prepper or a rural prepper. As he explains, a lot of it depends on the situation. In most long-term disasters, rural preppers will have the advantage. But in many short-term disasters, urban preppers will have the advantage.
But it also depends on the type of disaster. During a war or pandemic, you're much better off in rural areas where you can avoid the danger. But during a natural disaster, you're often better off near cities where you can get to emergency services you might need (medical, police, etc).
Of course, there's a lot more to it than that. Watch the video below to hear his thoughts on the subject.
