(Undated) — A new study says Texas cities are ill-prepared to handle a zombie apocalypse. Houston has the best chance of survival, ranking 28th out of the 53 largest U.S. cities. CareerBuilder based its research on eight factors including a city’s ability to defend against the virus, the ability to contain the virus and the ability to find a cure. Austin was the 35th best-prepared city nationally, Dallas was 40th and San Antonio was 41st on the list.
