Few years ago I was camping with a friend at a State Park and our camp site had a slight slope and at the end was an almost straight down drop. At the bottom was real thick woods. None of the hiking trails went through there. It was dark, maybe close to midnight, I was sitting on the slope looking at the stars and a rock was thrown up hill at my direction followed by sounds of something very big moving through the woods. Later that night in the tent her dog was doing a low growl and would not leave her side. She could hear something moving around the tent but the dog was acting like she was ready to defend us but not sure what it was. I checked the next morning and no signs of animal in the mud by the tent. In the grass about a foot or so away the grass was pushed down like something standing there with a really big foot. It was like it knew not to step in the mud really.
