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, we won't have to worry about ever running out of food because we have a massive fruit and veggie garden in our back yard, and we recently planted an orange tree and a banana tree. They are in good shape and have already yielded fruit this year.

Also, I have considered comfort in my plan. We have 2 gasoline powered generators and 1 bicycle powered generator that we will use to power electric fans so that we don't get too hot. 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 8-foot tall wooden fence. I acknowledge that a wooden fence is not the sturdiest, but we 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. I love them. My dad loves them. My mom loves them. My brothers love them. And, understandably, we have many. Among these weapons is my favorite, a surprisingly-well maintained home made flamethrower (P.S. It's legal where I live. I checked.), complete with spare nitrogen tanks and 50 spare magnesium-filled igniters. If a zombie manages to breech our spiky parameter, he will have at least 7 bullets and half a liter of burning gasoline in, and around his person. And it won't be just MY family defending our home, quite a few of my friends who live nearby are planning on coming over to my house with their families, food, and guns.

I know this is what you have been waiting for....
The Fail Safe! What am I going to do if my plan fails? I will light the fuse on the pipe bomb attached to our 3 50-gallon drums of gasoline and allow the zombies to fill our property. Once the fuse burns out, BA-DOOOOOOM! the pipe bomb and gasoline will create a giant flaming explosion that will consume all 4 acres of our property. Of course, all of the NON ZOMBIES (AKA family and friends) will have ran away as fast as we can from our has-been fortress. I just need to make sure that someone video tapes the blast and puts it on Youtube.
