As others have said in this thread, being prepared for some sort of environmental disaster or act of war is fine - better safe than sorry!
I'm a huge fan of zombies. Zombies are fictional. If you're really making preparations for a Zombie outbreak, might as well make plans for the inevitable invasion of crab-people, super-intelligent robo-rats or angry unicorns.
Links to photo of the firearms I own. I have access to many more modern and even larger numbers. Also a link to photo of one of two diver knives I own. I have camping supplies and plenty of water and canned goods. I have a generator that can power my home while the gasoline is available. I have plans for a wind turbine that can be built using a truck alternator, car, truck and marine deep cell (preferred) batteries and items from around my place. I have horses in order to get around when needed. Not that I'm preparing for an Apocalypse but If there is a natural disaster or total economic collapse I will have protection, food, heat some electric and transportation.
You all overlook one thing... The underlying (and actually stated) message of the Guide is to keep YOURSELF in a certain state. Pre outbreak, there is nothing more dangerous than a US Marine with a brain. Trained to kill, with a creative understanding of how to do it.
If I get a Mayday from some fat c*nt that can't pull his/her own weight, I might eat ya myself! Don't jeapordize a fit rescue group by being a blob! Sounds like MOST here have got they're head and fitness in order, and that is you're greatest great prep.
i have 2 months non-perishable food stored up in a mobile 65 gallon water proof heavy duty bin, strapped to a 1 ton capable movers dolly. i have long since finished gathering my own gear. (though, i am constantly upgrading it) and i have begun gathering surplus equipment, tools and supplies for additional people who may or may not be around me. i have an entire room in my house dedicated to this storage, though i just recently moved, and haven't had an opportunity to organise it and take pictures.
Just google, "survivalists" and you'll find a lot of news stories from the past decade. The survivalist movement seems to be cyclical, starting in the sixties, flaring up during the Cold War, and now returning because people are afraid of our government and global warming consequences.
I have posted here before but I will post again since I have actually made legitimate real world preparations for a doomsday scenario.
In the scheme of things, I find myself imagining any and every possible scenario that could occur and attempt to plan accordingly.
When I travel out of state I almost always carry with me a small assorted tool set, a deconstruction tool (combo Hammer, nail puller, drywall axe, crowbar) a large knife and a pocket knife. If legal, I will also transport one of my handguns and some ammunition although I typically leave these in a secure location and don't bring them with me. There was a great line in the movie "Ronin" in which a woman acts surprised that Rober Deniro had hidden a gun outside the place he was to meet her and his reply is "I never walk into a place I don't know how to get out of". I think this is good advice. Regardless of whatever likelihood there is that a major event will occur wherever I may be at any given time, I am constantly aware of my surroundings and their possible escape routes. What I try not to think of is..."What if I don't have [X]?" because thoughts like this serve no purpose but to muddy the water of your mind (that may have been me trying to sound like a man of wisdom and sounding more like a zombie nerd trying to sound wise...forget it...),
The long and short is that no matter what you prepare for and no matter what you do, the likelihood of your preparations actually helping you survive depends on the severity and intensity of the cataclysm. However, it should be noted that the likelihood of survival for those who have not prepared for anything still falls far below your own if you are prepared so don't give up!
