Here is a link to a brilliant, easy to use snake ID site that was created by the Florida Museum of Natural History;
http://www.flmnh.ufl.edu/herpetology...e/snakekey.htm
It's so simple - you just click on the color and characteristics you have observed, each time selecting from two choices for the one that best matches your snake. This will lead you to the final choice which identifies the snake.
