flashman,
Concentrate in the survival priorities, wich are:
1- Water: you can't have enough of stored water; a human can barely survive 3 days w/o drinking water; you must also have water storage and treatment means, like water treatment pills or a portable filter. Boiling does not garantee that your water becomes safe to drink.
2- shelter: make your home your fortress; prepare to defend it if necessary; hide.
3- food: store non-perishable food; prefer food that requires minimum water to preparation.
4- first aid: don't forget your first-aid gear.
5- tools: depends on your needs and your plan; the basics: something to cut, something to hammer, something to start a fire with, something to give you light.
6- at last but not the least: a PLAN! prepare accordingly, but expect the inexpected.
Knowledge is a weightless treasure.
