Fanatic

My plan would be to hole up in one of those isolated superstore Walmarts or Coscos, maybe even one with a gas station attached or very close. They would have all the supplies, bottled water, potential weapons, and entertainment you could possibly ask for. It would be easily defensible due to their limited entrances and exits, huge solid walls, flat roof for surveillance, and flat large parking lot that makes anyone approaching visible. I would image with the right team it could be easily cleared, claimed, and mantained like how the Walking Dead gang cleared the prison, but it should be easier because there are no regular live-in inhabitance of a superstore like there are in a prison and no armed forces would ever be sent to secure a superstore so no need to worry about killing zombies in riot gear.
