If a zombie apocalyse breaks out, the key to survival is being where other people are not. Get the people you want to get (if they are alive) then head out to the middle of nowhere with as much food and water as you can carry. It would probably be wise to pick up fruit and veggie seeds if you can find them. Guns would be nice, but ammunition will run out. So edge weapons would be necessary. Once you have your basecamp set up, forage/scout teams need to be readied and sent out every two weeks. No more than three people in a team.
Once things stabilize, then you can built a quarantine zone where survivors who make it to you are kept until they are proven to not carry infection. You rebuild society with the fragments of people who made it, always wary of the next zombie outbreak.
