Step 1: Prepare to Leave
First off: finding a place to wait out the largest surge of zombie hordes. The reason to get out quickly is leaving before everyone is infected and also to avoid being stuck in by blocked roads due to mass panic, police/military quarantine, giant pile of zombies, etc.
- If you're in the city: you need to get out of there! The idea is to avoid the biggest sources of zombies, which is where the largest population of people would be.
- If you're in the suburbs: it would probably be best to get to a more rural area, but your house could suffice.
- Already on the countryside? Perfect.
