Don't forget duct tape. It's #53 on the Top 100 Items to Disappear First - according to survivalists at The Power Hour. When it's Mad Max time, and location, location, location will refer to the best place to hunker down and defend you and yours, perhaps you will wish you had gone shopping with these items in mind. Me, I've got lots of cast iron cookware (#50) , but I'm a bit low on portable toilets (#3), not to mention and chickens and goats (#100). Some of the items likely to become scarce after the Apocalypse might not be true necessities - candy and cigarettes - but could be useful in barter and bribe situations. Other things likely to be in short supply: Internet service providers. So you might want to print yourself a hard copy, and go shopping this holiday season. And if you decide to stock up on Big Dogs (#40), make sure you get plenty of dog food. Forewarned is forearmed.
