Ok, so I have my doubts that we're all going to get overrun by the walking dead some day. But having a phone that can last a couple of weeks on a charge, that's light and simple to use and can be unlocked to work on multiple carriers, is a great idea to put in your "bug-out kit".
Here's the CNN Article on the Zombie Apocalypse Phone.
I'd actually seriously consider getting a phone like this, with a well paid-up prepaid SIM card and one of those emergency battery-powered phone chargers. I've got a small "bug-out kit" that I keep at home, something mostly for natural disaster type emergencies where I know all the important stuff will be in case I need to get a flashlight / first aid gear / emergency knife / etc. in a hurry.
Any other readers out there keep something like this handy, and if so, what do you typically keep in it? What would your "fantasy bug-out kit" look like?
