There is a great way to find out. Take an old sandbox(or a new one ) and fill it with soft soil, keep it damp not muddy and check it every morning. You may be surprised to find out what visits in the night lol. Here ara a few links to help you identify tracks.
Now, go have some fun lol
Tracy, dont forget to let us know what you find lol
Good idea, but im a little to lazy right now. Happy Hunting, i mean, uh, tracking.
