When the news finally breaks out that the United States Government isn't going to be able to save us from an impending zombie invasion, My family and I know just what to do: hunker down and shoot the crap out of everything that moans. My plan is simple, and consists of 3 important elements and 1 failsafe.

Element 1- My dad does frequent community service at a dry-pack food cannery, and as a result our family has been given a one year supply of food for seven people. the food's average shelf-life is about 13 years, so it will not go bad. In addition to our plentiful food supply, we also have emergency toiletries that can be made into an outhouse in the back yard. Also, lots of medical junk. Lots.
If our food isn't enough, we have these crazy neighbors from Louisiana who go hunting like, every week (no joke) and they always bring home a ton of food with them. They are going to be the first people I invite to our house, so that while my family and friends are busy killing zombies, we will smell delicious BBQ over the smell of rotting dead.

Also, I have considered comfort in my plan. We have 2 gasoline powered generators, which can be used to power window AC units and fans. In Texas, outdoor temperature can reach above 105 degrees F during the summer, and we don't want to get heat stroke.

Element 2- Our house is surrounded by a wooden fence. I acknowledge that a wooden fence is not the sturdiest, but we will have a special counter-measure ready so that we don't have to worry about our fence getting torn down. What is this counter measure? 9 foot long lengths of rebar, stuck in the ground at the base of the fence and tilted at a 90 degree angle outward. The spikes are 1 foot from each other. The stupid zombies will march directly into the iron spikes and impale themselves, thus keeping them from reaching the fence.
In addition to a spike parameter, I will set up lethal traps around our lot.
Also, Our property is surrounded by a 3 foot ditch that we can fill with oil/kerosene/anything flammable. Zombies who walk through it will be engulfed in flame and quickly meet their demise.

Element 3- Firearms. Lots.

I'll keep editing it. It's not perfect. :D
