The Safest Place in the Midst of a Zombie Apocalypse...

I've actually put some thought into this for some reason.

 

I don't know about geographical location, but when you're backed against a wall (literally) the best place to be would be the roof of a house. Zombies are slow and lumbering, not known for good balance. Simply climb up there with nothing more than a stick and you can easily pick them off.

 

Of course a roof causes problems for the living in that your 'locked in'. Zombies tend to zoom in on areas of high activity and what's you're on...
