Other countries may boast of this and that, but nobody can touch the United States for poisonous snakes. We have about twenty species, most of them deadly, and Europe has only five or six, none of them much good. We have fifteen kinds of Rattlesnakes alone and nobody else has even one. [ There is a species in Central and South America, but it probably came from the United States ].
