  Surviving an Apocalypse (Theoretical)
  For those interested in the theoretical aspects of a zombie apocalypse, studies have ranked several Texas cities on their preparedness: 
  Fort Worth has been ranked as a top city in the nation for surviving a zombie apocalypse, thanks to factors like low population density, good roads, and access to state parks.
  Houston also ranked highly, attributed to its number of hunting/weapons stores, airports, and access to ports.
