The US power grid is still vulnerable to solar storms or EMP, one huge solar storm hitting us just right could send us back to the stone ages in a matter of minutes. It's kind of scary!
Totally scary! Be sure to check out Twitter if you are on there. They post a lot of stuff on there for CHEX. Just ignore the crazies!
