Did a bear get it? Did the conservation officer remove it during his morning rounds so a bear wouldn't get it? Did the person who lives in the house nearest to the roadkill clean it up? I don't know. I didn't see any people during our walk, and only a couple of cars.
I mentioned this to my brother who had recently come across the scene of a recent coyote kill this past winter and he agreed that 'no body' is actually more freaky than seeing the body.
