I like to go out hiking but am afraid I might encounter some dangerous snakes. This rough green snake is not. Hiking throughout North America in general and the Southwest specifically is a pretty safe activity. Most of our venomous snakes have an ingenious warning system. They have a rattle at the end of their tail to warn hikers when they've come a little too close.
Snakes have no interest in tangling with humans.
We are much too big to eat. They are simply protecting themselves from being trampled. Other species of venomous snakes such as coral snakes can be found in Arizona. It is very brightly colored with bands of yellow and black alternating with and yellow and red. The black bands never border the red bands.
