since i live on a island, all i have to do is blow the bridges inbound, then just build some kind of fort.
But, first, i would have to open my dads gun case, and i would be moblie. Mainly, get in a pickup truck, fortfiy the sides of it, and get some of my friends. Sure, its bound to arract zombies, but, 9 kids armed with rifles is sure to thin out the zombies.
