RUN
There is a Costco nearby, and it has lots of non-perishables. It's big too, there would be enough room for whoever was there. Chances are it's not completely looted either. You find a mall exit nearby and start running. Then you start to realize that this is the start of a cliche' zombie apocalypse. Accept that the zombies, well, didn't really seem like zombies. At first you feel endangered about running out in the open, in the daylight. But after awhile, you notice that the "things" weren't out in the daylight. You sometimes saw one hunched over in a building, looking out at you through a broken window. But so far you haven't been attacked, so you slow to a walk. You make your way into Costco. The first thing you see is big groups of people. The food up front is gone, but you still see the big crates of food up on the top of the shelves.
