1. Rob a gun store amoungst the chaos and steal all the weapons and ammo I can carry in the trunk of my car.
2. Temporarily barricade my home and hide in my attic for a few days.
3. (Riskiest part) Steal a big moving truck from home depot, drive to the supermarket and load pallets of food and water into the truck.
4. Load everything I can and drive to a light house thats a good distance away from shore. Unload all my supplies into the light house by boat.
5. Hope zombies cant float or swim.
I have put too much thought into this. Its my number one thing to think about before I fall asleep
