The first one is moss that was growing on a driveway culvert, I'm not sure where the shells came from but it made it trickier. Joan from South Africa was right on the moss with the first guess. She had the nuts from a mahogany tree on her site this week. Boy did I blow that guess even with two guesses. Check out her site. The second was a deer's footprint in the mud near home, this is a place the deer have crossing a lot and you can see the trail. Becky got this one, she must have a deer crossing her NC farm. She always has neat stories.
I found this shortly after I had seen seven deer crossing a railroad track bed.
The last is my gardens mortal enemy the groundhog. They love to dig under my fence and eat my vegetables. Willard was the first to get this one. He is a super wildlife photographer from the mountains of Pennsylvania. Check out his site for great photos.
