Schall, 49, had hiked to the top of Nevada Falls with his children and was barefoot after cooling his toes in the rushing water. But an unfortunate misstep near a baby rattlesnake led to a five-day odyssey that included two emergency helicopter rides, three days in the ICU, eight vials of antivenin and a shot of morphine to ease his throbbing leg pain. The small-business consultant said he’s grateful to be walking again after the traumatic experience, which was far more serious than he expected from such a tiny predator.
