If I have correctly identified the paw prints from a picture on the web, after the snow fell, a fox came (from Mass Ave?) across the berm left by the plow, down the driveway, across a pile of snow to the compost bin, turned around and headed back by a slightly different route. I expect s/he was disappointed - I haven't put anything into the bin since Saturday. I put stuff out all winter, even when it's too cold for composting to happen outside. I suspect the post-Saturday stuff that is in the bucket on the kitchen counter is composting, but it hasn't started to smell yet. I suppose I could tromp in the fox's prints to put it out.
