Remember: Good Fences = Good Zombie Neighbors
Along with Pittsburgh's three rivers, the only thing that protected the living from the undead in George Romero's 2005 film Land of the Dead was a giant electric fence. Well, if it's good enough for the Iron City, it's good enough for your house, too. If you can't afford an electric fence, consider building a tough, tall chain-link, wrought-iron, or cinderblock version (at least eight to twelve feet high) around your property. The local zoning board might take offence, but, seriously, man; this is a zombie invasion. Who cares about zoning?
