I've always felt the ideal Prepper situation depends on three essential parts:
1. Personal food and equipment storage.
2. Food production, 'cause sooner or later you will use up all your storage. Raising crops and livestock, fishing and hunting.
3. Network of support. Probably the most difficult, as it's not easy to know who you can depend on to watch your back, while worrying if they will stab you in the back. But one really needs other people in the long run, becasue you can bet there will be gangs of people looking to pillage you.
