What ill end up doing when shtf.
Under the assumption of post disaster and anarchy is rampant.
Once my personal supplies such as stocked food and water run out and hunting, fishing, and gathering food are not available you'll have to start grouping up with other survivors to share resources or start stealing from better supplied groups.
Weapons and ammunition are heavily abundant in the united states. You don't need to stockpile weapons with 10k rounds for each weapon. Just think back to the old Klondike days when travelers had to deconstruct their firearms into other useful items. Ill have a suppressed. 22lr, ar15, compound bow, and scavenge /take what other weapons I see necessary from wherever. Someone else will always be better trained with better arms than you. Stay invisible and pose no perceived threat. Lots of folks talk about having their hardware, but are you prepared to use them? Under what cases?
Learn how to construct and use old world hand tools. They have little volume, weight, and do not require additional power/fuel sources in order to operate. Get a mountain bike. Why walk when you can roll faster with more gear.
stock up on medications, antibiotics, and antiseptics. You will get sick and hurt. Improper hygiene will kill you.
If this really were a SHTF situation, then a running and roaming vehicle will draw a lot of attention. You're going to be car-jacked. Think of only using the vehicle for initial escape from a heavily populated area. Get to the country or wherever youre heading and dig a trench or find a cave to hide your vehicle. I'll use a front wheel powered 4cyl car then steal your tricked out diesel truck if I want.
What you'll really need is a survival mindset. What will You be willing to do? Steal, kill, canibalize those weaker than yourself?
Gather your gear, form a trusted and trained group, know where your local and non-local resources are located, avoid the common areas, and get smart.
