Wait. Can I not fly to Galifrey?
Duh losers Time Lords always win.
Reasonable:
Considering the zombies are infecting 1.58 people per minute I'd have to say a mall isn't the best idea if someone gets infected, yet alone a whole horde of zombies. I'd get the neighbors together in a house, but not too big. Of course, no one I know has weapons what so ever, we'd have to use tools, such as a hammer 'n' stuff. Of course, we would simply abandon the garage, as we could suffocate. Of course, I have a lot of a residents in my neighborhood so that means lots of food. in the worst scenario if zombies infected our area we would not anywhere but underground. There's only so many ways in and if we threw some grass over it zombies wouldn't tell. The next step is to expand. Expand so much you don't even know. Then build a living residence big enough for a few cities. Being underground there's plenty of dirt to farm with so it's food central. Next is, considering at least ONE person brought a device, we'd contact other survivors around, encouraging them to do the same thing. If they did, we could tunnel our way over there, as they would us, expanding even larger. Eventually, zombies would overpopulate the food and die out therefor making us supreme rulers of our population. Of course, I'm only ten so that's my point. Not very ''possible'' I might say, but it could work. You never know.
