*cracks knuckles* Let's make this club even madami awesome.
1.) Food. Unlike zombies, we humans need pagkain to survive. When the apocalypse comes, make sure to have lots of it that will last a while. No items that need refrigeration, though. Canned foods are best, and make sure they're healthy. One of the last things you want is to be chubby.
2.) A Base. You need a base of some kind. Whether it's the roof of your house, a store in a shopping mall, or a van, make sure you have one, and make sure it's safe. Locks, metal doors, and retractable ladders are nice.
