This man didn't shoot the zombie until he saw the whites of it's eyes. Don't make this mistake! Remember: when they are up close, zombies are bitey.
There isn't a man alive who hasn't given serious thought to how he'd secure himself and his family In The Event of Zombies. We already know the best escape-routes, choke-points and where to build the barricades. Hunter-gatherer milieu? Yes please - then we can be awesome again! Well anyway, I never said we were sane.
