and unboarded. The only entrance and one or two outside staircases could either be barricaded or destroyed once the alarm is sounded. Secure on this raised platform, survival time would be determined only by the amount of provisions a homeowner had stockpiled.
    There is another highly protective dwelling that was built to combat a force just as prevalent, and just as deadly, as an undead army: Tornado-proof “safe houses,” now being constructed in the American heartland, are designed to resist mild to moderate twisters. Their layout consists of concrete walls, steel-reinforced doors, and steel shutters neatly concealed behind everyday curtains. On their own, these domiciles could withstand both a Class 1 and Class 2 outbreak.
    B. Modifications to Houses
    Securing a house against the undead is similar to securing it from the living. One difference is the common burglar alarm. Many of us sleep securely at night only because our alarms are “armed” and working. But what do these devices really do, other than send a signal to a private security or police force? What if these forces don’t come? What if they are occupied with other battles? What if they are ordered to protect areas deemed “more important”? What if they have ceased to exist, disappeared into the stomachs of ghouls? In any of these cases, direct means of defense are called for.
    Security bars on doors and windows will stop a group of zombies for a limited amount of time. Experience has shown that as few as three walking dead can tear them down in less than twenty-four hours.
    Tempered safety glass prevents entry by smashing but can be forced right out of its pane. This can easily be fixed by installing concrete or steel frames. However, the money it would take to replace each window in an average house could and should be spent instead on purchasing or building one of the two house types discussed above: stilted or tornado-proof domiciles.
    A good ten-foot chain-link fence can hold dozens of zombies for weeks, even months, provided their numbers remain at Class 1. A ten-foot cinder-block wall, reinforced with steel rods and filled with concrete, is the safest barrier in both Class 1 and Class 2 outbreaks. Zoning laws may prohibit a wall this high, but don’t dismiss it. (Check with your local zoning board.) Although zombies have been known (on rare occasions) to hoist themselves over obstacles as high as six feet, this has never occurred en masse. Several people, well-armed and with good communication, can maintain a six-foot wall, not easily but safely, for as long as the stamina of this group holds out.
    A gate should be steel or wrought-iron, solid if possible. It should slide to one side, not swing in or out. Reinforcement is as simple as parking your car up against it. Electric motors make opening easier but will leave you trapped in a power outage or breakdown.
    As stated earlier, a ten-foot concrete wall will only provide adequate protection in a Class 1 or Class 2 outbreak. In a Class 3 outbreak, enough zombies can, and will, climb on top of each other until they form an undead ramp right over your wall.
    C. Apartments
    Apartments and apartment buildings vary in size and layout and, therefore, in defensibility. However, from the squat two-story buildings of Los Angeles to the concrete and glass towers of New York, certain basic rules apply.
    First-floor apartments present the highest risk simply because of their accessibility. Tenants living above the ground floor are almost always safer than those in any type of house. Destroying the staircase effectively isolates the rest of the building. With the elevator turned off and the fire escape too high for a zombie to reach (strict limits are imposed by law), any apartment house can become an instant haven from the walking dead.
    Another advantage of the apartment complex is its large population. Whereas a private homeowner may be forced to hold the residence by himself, an
