You read the title Zombie Survival Plan. Sure you say they don't exist but it helps to be prepared just in case if Zombies do appear.
My plan is to get as many survivors as I can, and then head to a Bass Pro Shop. We will then stay there for awhile collecting supplies, then move and try to reach the river with a boat and get out. Luckily Bass Pro Shop has some great boats.
I'm going to immigrate to northern Canada and embrace the hunter-gatherer life. Constantly on the move. I'll bring my trusted, fictitious bloodhound and a machete. Of course, I must adorn myself in many furs to keep me warm.
That cold temperature of northern Canada? Zombies can't take it. They'll freeze after moving so long in the cold without thermoregulation.
If they don't freeze, the bulky denizens of the North will finish them. Like bears. And moose. If you remember my very, very old thread from long ago, you'll recall that moose can get pissed off quickly.
