Hey, that pic looks just like the one that was caught and released on Saturday. It was over by the Arizona pool, a guy caught it, we counted 10 rattles, plus the nub, and then he took it up the hill above the beach area and released it. The guy had handled snakes quite a bit and said that even though this one was quite docile, most of them are NOT and should be avoided unless you have dealt with them in the past.
Great pic by the way!
