Climb up on the roof on our school, its the perfect zombie fortress and it doesn't lie far away from two food stores and two fuel stations.
We would also bring batteries, swords from the local museum, computers, xbox, tents, TVs and other stuff.
The cool thing is that the school is impossible to climb without parcour experience or a latter, and zombies does not have the intelligence to use any of them while I have. And if we need water or "smartness" its a school with supplies right under us.
I would mostly bring my male closest friends, actually I would only bring the ones I know that thinks: me and my group is more important than other survivors. Because emotions often comes in the way.
I would actually only bring the people that fits these qualifications:
-I must be stronger than/ or be able to outrun everyone in my team - so betrayal would not be a problem.
-He or she must be 100% mentally fresh.
-It must not be a weak slow person that will slow down the group.
-Most important of all the person must not be annoying, because having an awesome unused sword and an annoying guy on your side would be pretty hard to tackle.
That was my zombie plan
