I'm beginning to suspect that Walt Tornow has the ability to cue animals in Sabino Canyon. Fortunately, Marty was on hand to capture another of Walt's sightings - this time a Black-tailed Rattlesnake. Mornings are now too cool for snakes, but they still like to come out when it's about 80+ degrees Fahrenheit. (I saw a Western Diamondback in late-November several years ago.) Be aware!
