Well, like a city wide outbreak? Well, I'd find a mall and set up fort there. But before that, I would listen to the news on possible evacuation points then set off to find my friends. If they haven't been zombified yet. Of course, I would need a mean of transportation, so I would use my bike. Ride to my friends houses and find them. In a zombie infested city, allies are essential. So, we ride to the nearest mall. We would stay there until we can think up another plan.
