A lot of preppers prepare for a catastrophic event, I personally think in terms of a minimum of 3 years of preparations is a good measure although if rich or so situated I would go for 10 years.
Getting hung up on the Road Warrior stuff is a distraction from most useful prepper discussions, just as were all the years of survivalist discussions getting hijacked by turning them into arguments about how many guns and of what type, for decades almost every survival discussion immediately went to guns and shootouts.
I have to say ..I don’t know what this road warrior stuff you keep mentioning.
Don’t own a tv and I haven’t been to a movie in over 20 years.
I’m going by what I’ve read long before the internet consumed the world.
And more recent events which I have gleamed from the internet.
And what makes the most sense in a catastrophic doomsday situation...
for a inkling consider the people that loot for much less of a reason(x 10..x50 in a shtf situation)
BTW I suspect you would shoot a looter tring to get into you’re 3-5 year supply?
