My workplace is nestled up against a mountain range. All the coffee-swilling, tree-hugging, fitness-crazed, Ph.D.-laden people who work here often take their lunch break and go for runs up the canyon nearest the back of the facility. We regularly have deer of various varieties on site and are quite used to close encounters with wildlife. (Last year, though, one coffee-swilling, tree-hugging, fitness-crazed, Ph.D.-laden bicyclist actually ran into a deer last year and died! It was truly tragic, but quite bizarre.) You could say that we've become jaded to the presence of animals of every variety and the runners don't even flinch when they see something new. Yesterday, though, somebody saw the mountain lion pictured below stalking the runners. Needless to say, the coffee-swilling, tree-hugging, fitness-crazed, Ph.D.-laden runners aren't running today.
