Realistically if zombies go active then the majority of us are fuked. There is going to be a hand full of people in the world that are good enough with various weapons, navagation and survival skills to actually survive long term.

I am pretty sure 20,000 rounds of ammo isn't going to help, as thats way to heavy to carry. Yes vehicles may still be operational, but will the roadways? In other words i ask what is your plan to get food, weapons, supplies, friends and family from their houses to safe house that preferably has some sort of fortification.

THis question goes true for a varity of shtf scenarios: presidential assassination, NBC attacks/ natural spread/ industrial accidents, etc etc etc. Just food for thought.
