The Western Hemisphere is not only the origin of corn, potatoes, and tomatoes, but also squash and pumpkins. Carrots, probably purple at first, were from Afghanistan.

The ring neck snake is mildly venomous, but don't worry, it uses the venom to kill frogs, worms, pill bugs, and lizards. The venom though is to mild and delivered in too low a dose to harm a human. Ringneck snakes secrete a foul smelling odor when frightened.
FACT: A lot of snakes have patterns. And some venomous ones don't have any pattern. It seems that just because of diamondback snakes or coral snakes, people think that snakes with patterns are dangerous. But most common harmless snakes, like Garter Snakes, Corn Snakes, Milk Snakes, etc. have distinct patterns.
