Camped outside Sedona Az. spring of 2016 near Palatki ruins. I noticed an interesting rock on the ground near my right foot. As I reached to pick it up I felt a sharp sting on my right wrist bone. The rattler recoiled, I guess for another strike, needless to say I vacated the area. It never moved, rattled or gave any indication it was there until striking. I loaded the dog and myself in the truck and drove to urgent care in Sedona. The PA listened to my heart took my blood pressure and cleaned the bite. He said if it swelled any further or became more painful to go to the emergency room otherwise go back to camp. The bite was directly on the wristbone and most likely didn't get much venom injected. The only thing remaining on the wrist is a single red spot. Wish I could say that about the moose attack my dog and I survived later that summer in Grand, Co.
