There is no mistaking this traffic signal, or is there? I was already in retreat before realizing this was not a skunk but rather a black squirrel with a white-tipped tail. Once I was sure it was a squirrel I found its tail a beautiful sight amidst the delicate looking flowers in a garden beside the MSU library. F3.5 at 1/500, ISO 800, 80-200mm lens at 200mm
