Way to Surive Initial Outbreak

GET AWAY FROM OTHER PEOPLE
That is the most intelligent thing you'll be able to do when the dead hunger for your flesh. Think of living people as chum, and the zombies as sharks. The more chum, the more sharks. You do not want that, for reasons which I feel are pretty obvious(You'll be eaten alive).

It may sound a bit heartless, in any sort of disaster you'll worry about your loved ones. The emotional attachment will make your survival very difficult. You won't be able to do the things you'll need to to survive if you're constantly worrying about other people. And like I said, it does sound heartless, but if they're dead weight drop them.

A zombie apocalypse is no place for baby sitting. You do not want to have to carry around someone who will complain about everything and break down every few hours. If you find yourself with someone like that, take it upon yourself to end their suffering.

YOU CAN CLIMB ZEDS CAN'T....... WELL
Get to the mountains. It doesn't have to be a hardcore climb, any trail on Oahu will do fine. Make sure it's easy for you, but hard enough that the zeds will constantly fall. The way to judge this is, if you can't get up it without constantly grasping something near to steady yourself, zeds won't be able to get you.

The Lanikai trail is ideal. The first climb is very steep and you wouldn't be able to get up without holding onto the surrounding trees. Also the entrance is very low and narrow, you could easily block it with a car or anything really. You can only go up single file at first, so just up root some small trees and block it off. Then the cherry on the cake is that there are pillboxes up there, you're able to get some construction supplies up there they would make very good shelters.

The trail leading up to the rocks behind Kalaheo is also very good, but you don't have the luxury of a pre-existing shelter there, so at best it's temporary until the majority of the population are zeds. At which point you could come down and take what you need from where you need, just watch out for the zombies.

IF YOU MUST SAVE YOUR LOVED ONES
I can't tell you how long the electricity will stay on, or how long you'll be able to use your cell phones, so get a message out to them as soon as possible. The message should contain the following:
A rendezvous point
Your name(just incase they forget)
A necessities only warning
A warning not to come anywhere near you if they are infected

Do not go looking for them, save yourself. If they were smart enough to survive they'll find you. Beware of other survivors, you don't know what their state of mind is like. Make sure you keep your rendezvous point secret. It'd be tragic to survive the zombies only the have some thugs come and kill you for whatever you have.
