It's certainly a good idea to be prepared in case of emergency, but there's no need to be insanely over-prepared. If you'd like to be prepared to a reasonable degree without spending $15,000 on a bomb shelter or keeping hundreds of pounds of dry goods in your basement, just get a Blackout Buddy.

The Buddy chills on an unused outlet most of the time, getting' all juiced up. As soon as the power goes out, you get a flashlight and AM/FM radio that'll last for 12-16 hours of flashlight or 4-8 hours of radio use. And for only $30, it's planning ahead without being a complete psycho about it. — Adam Frucci
