I would be the final survivor

like many of my previous prompts, I will be writing about my zombie apocalypse plan.
First, upon hearing the news about the apocalypse, I would immediately go and raid stores that own a ton of guns and weapons.  I would then gather around 20 people top join me in my survival. These peopel would have to be in shape so they can outrun the zombies, as well as smart to help think of strategies that would best help the group. From this point, I have three alternative plans to what I would do.
plan 1: I would take my survival group to the atlantic coast, steal several boats, food, medicine, etc. and travel to an island just off the coast. I would clear this area free of zombies and live there for the rest of my life. I would leave instructions, once I die of old age to the colony. That once they reach a size of 200 people, go back to the mainland and try to survuve there.
Plan 2: This would just be a plan for kicks, but I would barricade my group into a sam's club. Because they have so much food and water that we could survive there for a long time. Plus if we somehow get over run by zombies, we could just live up on top of their food shelves stacked to the ceilings. We could have a whole traveling network up there.
Plan 3: I would go out into the middle of nowhere, like nebraska, and go inside a jail and live there. With reinforced walls, and electric fences, it would be impossible to breah and lead to a life filled with happiness in the slammer.
