Nomad proles didn’t flourish in densely urbanized locales like Massachusetts, where video surveillance and police search engines made them relatively easy to identify and detain. But Green Huey wasn’t from Massachusetts. He was totally indifferent to the standards of behavior there. Louisiana’s ecologically blighted areas were ideal for proles. The disaster zones were also impromptu wildlife sanctuaries, since wild animals found chemical fouling much easier to survive than the presence of human beings. After decades of wild subtropical growth, Louisiana’s toxic dumps were as impenetrable as Sherwood Forest.
