I would go to my friends house (they have tons of guns) then drive with them to my other friends house (also tons of guns), then I would drive to a Costco and build defenses all around it. Then, get a car and turn it into an armored vehicle (awe ya ) and drive to a gun store and pick up all the amo and guns. Whenever we run out of amo we make another run in the armored car. We would let in any survivors who needed help (but no one who is infected). Eventually we would go to an abandoned dam somewhere in a forest, fix it up, grow some crops, and then you have a fully defended fort that is self sustaining.
My plan in case of any type of zombie apocalypses.
