The Centers for Disease Control and Prevention is always looking for ways to get people to think about worst case scenarios, and take plans for their family's safety. Yesterday, in a much publicized campaign, they issued a post describing how to prepare for the coming Zombie Apocalypse.
Their contention, which I share, is if you're ready for zombies, you're ready for anything. I thought the post was well done, and it drives home the need for a personal and family emergency plan. They even explore the various kinds of zombies - undead, infected, rage virus, and so on. Of course, they end with the conclusion that you need to have a plan and provisions.
My only beef is that the post totally ignores the obvious advice of what weapons would be best to combat the undead horde. So, where do we turn for that kind of practical advice?
Fortunately, there is another group who has had the same goal for a lot longer - the Zombie Squad. They started in 2008 as a zombie fan site, and found that they kinds of things their members talked about in the forums to fend off the zeds, worked just as well for emergencies that were less civilization-ending, such as hurricanes, floods, and tornadoes.
The Zombie Squad Forum makes for very interesting and thorough reading on the topic of surviving just about any level of emergency. The sections on survival equipment - including weapons - is especially useful. I recommend you take a look, spend some time there, and heed the advice that fits your situation.
Then, make your plans and get your provisions ready. No matter what your motivation, none of it works without action.
