​My experience takes place on Rough River in Grayson County, Ky. My good friend, his wife and I were on his boat in a scicluded part of the of the river. We were at least a mile from anything or anyone. We had been fishing for about two hours enjoying the mild fall weather. We like to fish for strippers. ( Stripped Bass). The boat was anckored in the middle of the river, about 40 yards from the bank.  Just about dusk it happened. Large rocks, (cantaloupe size) started landing in the water all around the boat .About six, they were being thrown from the wood line to our right. We never saw or heard anything, no crunching of leaves, no snapping twigs, no sound at all just huge flying rocks. Feeling a little bit bothered we decided to move to another good spot, so we pulled up anckor and moved down river about 3/4 of a mile to a bend in the river just near an old country road bridge dropped anckor and resumed fishing. Slightly after nightfall about an hour and a half after moving, the rocks started falling again. All around the boat. Again ,no noise. Just the rocks splashing into the water around us. The river is completely surrounded by thick woods. Mind you it's fall and there is no way anyone could move around in them without making any noise. I grew up hunting and fishing my whole life and I know the woods and it's sounds. This time of year the leaf cover on the ground is very noisy. Now we became a little fearful, we all looked at each other and said time to go, and headed back down river to the boat dock where my buddies truck was. We loaded the boat without a word and headed home. It was about a half-hour before anyone said anything. We were all still shocked about the whole thing. I looked up and said, had to be a big foot. There was an immediate response of agreement from both my companions. We talked about it the whole way home.  Now I'm a large man,  6' , 350 lbs and am quite strong, even I could not have pulled off what happened to us. No noise, and throwing such large rocks as far as they were. Now I can't say for sure what it was but I can say it wasn't a man. This really happened to me around 2016- 2017. I'll leave you to draw your own conclusions.  But I know what it was.         Eric Surgenor
