RE: Prepping my bug-out cave for the possible coming collapse of civilization
The way I see it there is at least a decent chance it won't come that far, and I do get where you are coming from. If you feel the need to prepare in this way do it, and it's kinda nice to have a well-prepared spare cave anyways ahahaha.
When I read your article I was thinking of the primitive technology dude, might be of great use if you aren't already familiar, though his environment is more jungly.
All the best to ya <3
