Porcupine hiding behind the tool shed

I came around the corner of the house this afternoon, carrying tomato cages to the tool shed, to find a porcupine waddling across the yard. By the time I could get the camera, it had climbed into a pile of scrap lumber on the back of the shed. Cute little bugger. They look cuddly, but I know better. Hard to resist giving him a pat, though.
