It's easy to feel uneasy while driving through the desolate desert roads of Arizona, especially at night, and particularly so when you hear a short burst of taps on your window while cruising at 60 mph and turn to see the shapeshifting, mutilated, half-human creature responsible for the high-speed interruption.
Relax -- it's only trying to rip the flesh off your bones.
This legend is so ingrained in Arizona culture that, when a Navajo woman was found brutally murdered in Flagstaff, the accused killer's defense in court was that the attack could have only been perpetrated by a Skinwalker.
There's even a defined and well-documented portion of the state known as Skinwalker Ranch where you are most likely to see one of the creatures. Not that you'd actually want to.
