Urban Exploration

Exploring the underworld of modern cities. In this case, New York. I think that urban exploration could be important practice for a zombie apocalypse. If there was a zombie outbreak, you may need to move around (or even out of) a town or city while avoiding zombies, or to escape a quarantine. (I understand why a government would need to quarantine a city, but that doesn't mean that I would want to acquiesce to it in my case). In a post-zombie apocalypse world, you will need to scavenge food and supplies, again while avoiding zombies, and perhaps other, less friendly, survivors.
