For the second time in as many weeks we ran into a porcupine on a trail north of Vail, Colorado. She was huge and a mamma walking toward Teig and I. She couldn't recognize us until she was about 25 feet away. Luckily, Teig was on leash at the moment and their was no altercation. I let her move to a nearby tree and climb up about eight feet before getting this photograph of her where she felt safe. She was gorgeous.
