If I found myself where my town had become over run by zombies, I would book it to my town's school. Now, your probably asking yourself, why the school, and there is a few reasons.
1.) most high schools are designed to keep unwanted people out, so that includes: heavy doors, security cameras, and other security devices.
2.) schools have to provide food for hundreds of people, so you know that you will have at least a few supplies.
3.) during a zombie attack, either the school will go into a lock down, insuring you have some non undead inside, or it was evacuated early and few zombies will likely populate the school, insuring safety.
4.) the school i speak of is right next to the national guard center, so guns and other survivors.
