I hitch hiked to Arizona back in the '70's one time. Hicking back home I slept under a pick nick table coming home. I woke up in the morning the whole underside of the table was covered in scorpions, must have been a thousand. I wiggled out from under there and never did that crap again.
That sounds heart attack inducing, almost as bad as waking up surrounded by rattlesnakes.
I've got a friend in Phoenix that tells me the scoripons are terrible there, especially in his neighborhood. That and rattlesnakes.
