Western Diamondback Rattlesnake hanging out at a conveniently-provided rock wall with some deep holes in Ahwatukee.

This means that landscape designers have a lot of control over how many rattlesnake encounters will be at a home – much more than the common perception of “ur near the desert u will see snakes” that we see so often.
