There's an area not far from where I live (midwestern U.S.) where I've seen numerous snakes. You can just be walking out in a grassy area, and snakes dart left and right trying to not get stepped on. Totally harmless, unless maybe you tried to annoy them. But I'm guessing you'd be most interested in avoiding more harmful snakes, like, how to avoid being killed by a python or some-such. I too have only seen pythons in zoos.
