Go up to my friend Nick's house and grab those shotguns, get in a truck or a car, get a lot of gas, pick up anyone thats not infected, get more cars and guns, go to a harbor, get on a boat, go to the Nearest Military base.
And the Government will do marshal law and kill anything that moves at them, bomb infected cities and roll in with tanks and helicopters.
I'd sit down, read a book and wait for my inevitable demise. Let's face it, I live in a heavily populated area and I probably wouldn't make it out of my neighborhood let alone the city. In my case, I'm fucked. Might as well accept my fate.
Well this is a failproof plan.
1. Steal a boat
2. Steal supplies and tools required to survive in the wilderness.
3. Get more survivers.
4. Go on an island unpopulated by humans, or just populated by too few humans.
Zombies can't swim hence you are safe and you saved humanity from peril as a species.
If it started while I'm at school, it's going to be one hell of a trip back home, but worth it. School > Walk to City Hall > Peninsula Plaza is a quiet mall which has a military shop and also a sports shop > Search for supplies from any 7-11 stores or any mega markets > Walk home from there (2 day journey by foot) > Camp in a friend's maisonette for a few days > Take the minivan and go over to the beach as my are is very close to the beach and also near a military island in Singapore > Get a boat to go to that Military Island or just move on to any other island.
