Like alligators (everyone else has crocodiles and caimans), rattlesnakes are found only in the Americas.  Huey wondered where they got their rattle. After several difficult months and the freedom of information act, he  discovered that rattles were grown in a covert, organic rattle farm in Oregon and drop shipped to each rattlesnake several times a year, no charge, courtesy of the government.  Now, lack of funding made it likely the program would be cut, and another unique North American species would become ordinary.
