And also, why does everybody want to pack an armory and raid the gun store first thing? Don't you realize that 1. Food and gas will be much more valuable than guns, and more useful to you
And 2. That's where everyone else is headed, avoid the stampede.
Decent fortifications and some melee weapon should be the bare minimums to keeping the zombies away, food is something else you need, water also because I'd imagine most water would be bloody/muddy and like a petri dish.
