   Fort Jefferson

   Fortified Structure

   Fort Jefferson offers moat, masonry and open-water separation far from Key West. Twenty survivors can find substantial shelter, but Garden Key’s primitive facilities do not provide the food, drinking water or fuel needed to stay.

   Alcatraz Island

   Fortified Structure

   Alcatraz places a steep island shoreline and substantial Cellhouse between twenty survivors and San Francisco Bay. Its difficult landing approaches buy separation, while drinking water, food and waste handling remain tied to mainland logistics.

   Guantanamo Bay

   Institutional Compound

   Guantanamo Bay has housing, utility infrastructure and its own drinking-water production. Its difficulty is scale: a small group must keep essential services working inside a sprawling mainland installation without inheriting the Navy’s workforce.
