Alright, let me throw in another US state, a neighbor of two states I covered earlier Texas and Arkansas, Louisiana.
Cities in Louisiana that could use a major AZA-Accredited zoo include the following;
Shreveport - Population of 187,593 at the city level, and a population of 237,848 at the Metropolitan Statistical Area level.
Lake Charles - Population of 84,872 at the city level and a population of 216,785 at the Metropolitan Statistical Area level. They have a state university, McNeese State University which used to have a natural history collection, why not a zoo?
Lafayette - Population of 121,374 at the city level and 241,753 at the Metropolitan Statistical Area level. They have a good science museum with extensive natural history exhibits, why not a zoo?
Houma - Population of 33,406 at the city level and 109,580 at the Metropolitan Statistical Area level.
And
Hammond - Population of 20,019 at the city level and 121,097 at the Metropolitan Statistical Area level.
