>> If you can get close enough, you can look at the eyes. Non-poisonous snakes have round pupils like we do, but poisonous ones have vertical slits like that most evil of all creatures, the cat.

Um, almost....
Rosy boas have vertical slit pupils too.

Its actually alot easier to identify venomous snakes if you're in CA... I believe they all have rattles.
