Ah, the list!!
A generator, a portable solar panel (preferably one of those folding mylar type panels)
At least 10 gallons of gasoline and keep the car or cars above half tank and at least one full.
I'll second the canned food supply, at least 6 months or more depending on your storage space.
Of course, ammunition. You can never have enough.
At least three oil lamps and two gallons of lamp oil.
Two butane single burner camp stoves and 24 canisters of butane fuel.
Provision for storing at least 500 gallons of water, I have a spa, some use the bath tubs for storage.
Strike anywhere matches, 5 boxes.
Magnesium fire starters.
If no water storage is practical, get a water filtration system, like a Sweetwater.
A hand ax is a definite requirement as are good knives.
100' of Para cord.
Two large tarps
30 gallons of your favorite alcohol. If you don't drink, it is trading stock.
If you plan on bugging out.....
You will need adequate shelter, clothing, be prepared to hunt and fish, live off the land.
You will have to get there, 4X4, ATV, Motorcycle and trailer.
You will have to pack all your food, ammo, camping gear, everything with you or you're dead.
Trust no one, even neighbors, and especially those who haven't prepared.
