Every state has it's blue holes.. California = San Francisco, Minnesota= Minneapolis/ St Paul, Michigan= Detroit, Oregon=Portland, New York=NY City, Georgia=Atlanta,
Indiana=Gary, Illinois=Chicago, Kansas=KC, Missouri=St Louis, Nebraska=Omaha..... and the beat goes on.
IMO; citHy dwellers..hogs, pigeons, baboons, elephants, chimps and prairie dogs...all run in tight knit bands.. Some kind on mob mentality..
Not lately to change soon !
