im not sure guns would always work, and then if they did u would need ALOT of ammo, i would grab some hunting knives, a machete, a sword exc... and id raid a REALLY big store, id live there with my friends, we'd have water, food, and weapons, and either wait till it was all over, but if a zombie broke in we would attack together, and we'd wait till the army did something about it, but if a zombie has almost killed me, id kill myself, not gonna let the zombies have the pleasure of killin me
