Why not both?
But if I had to choose - ZOMBIE MALL
Okay, I still fantasize about getting to go on a zombie killing spree before I get eaten alive. I mean, how many of these bastards can I get before I go down? The sad truth is, no matter how badass you are, you will still get eaten by zombies eventually if you plan to never go down.
But think of the possibilities!
Zombie killing gameshows!
Zombie Zoos!
Zombie Child Prostitution Rings!
and it only gets better, you know how we humans tend to "enhance" the actions of nature. Ha ha

So, as the world is spiraling out of control, and people are turning zombies into pets, and we are making a sport out of these ex-humans - I would love nothing more than to post up net to a gun store and tally how many heads I can shoot off.
