[Flashpoint]

Couldn't you just dig a 12 foot deep rectangular "moat" (dry) around your perimeter and call it a day? Zombies fall in, and can't get out. Once you have enough, you just push the dirt back in and crush them, brains and all.

Of course, then you'll need to re-dig the moat, or perhaps move to another location. And this assumes you aren't under constant attack by huge numbers. Although in that case, you could just put a plank over the moat and walk over it and away.

Thoughts on the impending and inevitable zombie apocalypse?
