I think I would rely on the unofficial militia I have formed in my township.. it consists of about 5-7 people, you know the regulars level 1 IRC wizard.. and the rest are rambos.. I stock up at my house with tons of guns, since we have a gun room, and honestly if you have a gun room you are set since there is many diffrent sorts of guns to choose from... Then I would go up the hill from my house beating my way through the zombie hordes trying to eat my neighbors, along the way picking up squirt guns and fending off the regular zombies as to conserve my ammo and then I would steal a big suburban since those are designated in our milita as urban assult vehicles... then we would probably procceed to hit up the out of the way gas stations for food, water, and gas, and then either go out in a blaze of glory and try to kill as many zombies as possible or leave town... heh knowing my friends we would probably try to go out in a blaze of glory, heh you know try to set as many buildings on fire as possible
