I'm on the sixth (top) floor of my building. I need to stock up on food and water and get myself a sniper rifle. I then need to block off the stairs (a la 28 days later) and wait. This method is recommend in the zombie survival guide. I will keep my copy of it handy at all times, a long with world war z and the walking dead graphic novel compendium. I also have zombieland, Shaun of the dead and 28 days later on DVD for revision, and left 4 dead 2 and dead rising for practice. Hope I'll be ok.
