Humm well considering I already know what I'm doing, yes I literally have a plan. First off screw guns, and anything that takes ammo. Keep in mind ammo means you have to carry it, and it could run out at anytime. I have read the Zombie Survival Guide, I own a copy. I also know someone who read it then made some changes to it. His nick name is Neff.
In the year 2012 the world is supposed to end. Now weather or not Zombies will come of it, is only one thing that could happen. Me, I'll be grabbing the only weapon you need. A crow bar. Best weapon of all. It can crush a skull, break open anything and is light enough to be carried around. Now I've heard people around me say they will go to a mall, or a hotel cause it's big. Well seeing as that's where EVERYONE WILL GO, I will head towards Neff. He has a compound with underground passages, chemicals that can damage a human body, and only one entrance that can be blocked off and secured.
I can't really say what anyone else should do, that's up to you. But here are things you should know. Learn how humans react to stressful situations, knowing what they do and how they act will save you a lot of trouble. In a zombie attack situation, DO NOT GO TO LOCAL HARDWARE STORES, WALMART OR ANYTHING THAT YOU THINK YOU SHOULD GO TO FOR SUPPLIES! Why? Everyone in driving distance will go there, and no most humans will NOT help you. If you live in a really cold climate, your pretty much all set. Zombies might be the walking dead, but their bodies still applies to the laws of nature. Freeze a corps, shoot it or destroy it somehow, it's not going to put itself back together. Remember dead bodies don't heal.
Keep your head, use your instincts to survive, and wait till winter held up in a safe location. And you will live.
I babble a lot when I haven't slept for a bit.
