you don't sound cocky at all man. Its awesome that you think highly of yourself, not enough people do! Its that kind of thinking that helps you push forward and take action and have mental reassurance. That's awesome that you're so clued up and have a lot of resources. At least every week i have to sit down, watch a zombie flick and study the brains out of it. I myself if a zombie outbreak were to occur have thought of thousands of plans. That latest being: if i were given a tine frame before hand i would dig a really deep trench all around the outside of my house so the walkers would instantly fall into the ditch. I would smash up my stairs so if they were to enter my house they couldn't get up. In and out would be through my window with a ladder, a retractable one, modified with knifes on the ends so i could use it as a spear weapon also. To either defend my self or pick them off from long range or down in the trench at ease. A fence and wall would also be surrounding my house, just in front of the trench, and a tunnel would be dug for passage in and out of my house with a heavy locked trap door camouflaged in with whatever the ground terrain is. Water purifiers are easy enough to build, boiling water is easy enough also. And as for food, i would have a vegetable and plantain patch in my backyard and would scavenge up as much canned food as i can carry. In case of an emergency if it he walkers overrun the house i would have easy access to my attic through which a window would open and a hand made zip wire would be ready to take me over to the nearest sturdy object, (whatever it is i attatch the other end to. A few concerns would be of course humans ready to jeopardize everything, infiltrated my house and wreck everything i built. And the the zombies being half clever, piling up on top of each other to climb the trench etc. I have loads of theories and scenarios but it would be way too long to type, not that this isn't already lmao.
