ALL of your needs should be layered with say navigation being GPS, then Map and Compass and even have some sat pics of the region printed up before the power goes off. And finally learn to navigate using the stars at night and shadow sticks during the day. Remember a simple sewing needle magnetized before the flare goes up or after by using a rock etc ....can be floated on a small leaf in a puddle or plastic cup and it will point north.
I am of the mindset of a few here......I bug out only after being forced by the event or the authorities . My system is layered with my home first and primary shelter with supplies that will get me thru without utilities just fine. Second are my motorhome or 5th wheel trailer with a towed vehicle or vehicle towing the trailer. Third just the vehicle, 4th afoot with gear in the form of a long term survival ruck with tools and gear that will get me food and water and shelter for the long term without support. Fifth .....on foot with maybe a small pocket size personal survival kit (psk), a Swiss Army Knife (SAK) or Leatherman Tool and a fire steel.
After that it’s down to making a fire with friction method, a squirrels nest / debris shelter and drinking from puddles and streams etc ......., gathering food with a rabbit stick . All without tools or gear of any kind. Just skills....... if such is upon me I am in deep trouble at that point .....:o)
My pockets have a small Swiss Army Champion, A Fire Steel, and a small altoid tin with some key goodies in it that will get me thru a few days in the wilds.
