Behold the Amazon lists. 

I don't have it all, but I want the umbrella/flashlight/stun gun combo. Bad. I am in process of trying to get an Amazon ID so that I can earn each time someone uses one of my links. But that's not in place yet, so it's all pro bono.

As you prepare, people may treat you like a lunatic. They're just trying to make themselves feel better about not preparing at all. Go out of your way to mention you'll cut a bitch who comes for your stuff so they won't get any ideas when they realize food/water/shelter is important.

Pro Tip: Make people slightly uncomfortable when you talk about this. You don't want to be their first call when they need shit.
