A Western Diamondback rattlesnake is shown in Cave Creek, Ariz., in this May 1990 photo. At the beginning of peak season for snake activity, including that of poisonous rattlers, some hospitals in the Southwest are concerned they won't be able to properly treat snakebite victims because of a shortage of antivenin.
