That’s right, I’m that guy. If it’s remotely capable of happening, I’ve probably got a plan, or six, and the supplies to deal with.
So, in this thread you can ask me things like, “Why the hell are you so prepared?” “What would you do in the event of [Insert Event Here]?” “Are you a nutjob?” (Probably) and more!
A bit of an example: In my car, I have a bag. In this bag, I have items which would see me through even an extended survival ordeal (indefinite), if necessary. But, this bag is small enough for me to carry on my own.
In the bag: A full change of clothing (Shorts, Jeans, Underwear, Tshirt, Hoodie, Undershirt, two pairs of socks), drier lint and flint (for starting fires, drier lint is takes a spark like mad), 4x3000 calorie bars (taste like shit), water purification tablets (a lot of 'em, they’re not very big) and a few boxes of water (like juice boxes, but filled with water) and a lot of gum. And a “trap guide” (incase I forget). The trap guide is like a farmers almanac of hunter-gathering, with basic stuff like telling you your location, what game is in that region, the best traps, etc.
I think I’ll also put a 10mm pistol in there, when I recover it and my boat from the bottom of the lake, or get a new one. 
You wouldn’t believe what super-sugary gum will do for you if you’re feeling tired while hiking.
There’s also stuff like my regular attire, which people thinks is weird. I wear Jeans and a tshirt, like everyone else, but I also wear two undershirts and thicker-than-average jeans. I can go out without a coat in almost any weather, and any but the hottest weather, I can leave all three shirts on.
ETA: Yes, I’m prepared for the Zombie apocalypse. Although not directly. I’m prepared for the zombie apocalypse by getting eaten quickly, and not having to be scared shitless for six months as they slowly hunt me down. That, or suicide. Not really sure yet.
