Report 9502: Young horse rider has daytime sighting near Ash Grove.

I grew up on a dairy farm, and would bring in the cows for the evening milking.  This was often done on horse back for both pleasure and convenience. Since I was only ten years old at the time I didn't have to actually milk the cows after they were at the barn, and could ride the horse while my brother and father milked. On the evening of the incident I was riding our appaloosa Gelding south from the barn lot toward the back of our farm. Most of our farm had been cleared by dozing eight years before, but the farm behind ours was completely overgrown,with trees,and brush, and it had not been used for anything for several years. The east boundry of our farm was a river, and there are many caves and sink holes in the area due to the karst topography.  As I mantioned above most of our farm was open so visability is good.  I had ridden about 100 yards west of the barn and was within about 100 yards of the back fence when Ace, our horse stopped walking. I kicked him in the ribs a little to get him going again, but he would only go a step or two and would stop again. This went on fow several minutes with me trying to force Ace who was a very well behaved horse to go forward.  I only managed to get him to go perhaps 20 or 30 yards, before he would go no further. All the while he was stamping his front feet, and snorting air out his nose in great puffs,as well as having his ears laid back against his head.  I was getting very frustrated with Ace, and was slapping the reigns against his flanks, and kicking my heels into him,but he would not go. At this time from behind a small cedar tree a large black humanoid  creature stood up, as though it had been crouched there hiding.  It turned toward the back fence of our farm, being just on our side of the fence.  I took four or five long strides walking upright then jumped the fence like a man would jump over something, rather like a great hop. I didn't get a chance to watch what ever it was because Ace turned and bolted back for the barn, and there was nothing I could do to stop him. I was barely able to stay in the saddle he was running so recklessly. I got my father and brother, and we went back to where I saw what ever it was but it was long gone. I remember that it was not covered with long stringy hair as these things are often reported, but was very dark from head to toe.I saw it from about 60 to 70 yards away,clearly with nothing between us until it jumped the fence. It was probably 6:00 to 6:30 pm, but it was only late September so it was still light out at the time.There were other occurrences in this area with screams, or cries at night, the sound of crashing movement in the brush near our house, and a putrid,rotten smell that when smelled while coon hunting would cause the hound to come back to us, and they would slink around at our heels with their tails between their legs. These things took happened over several years, but mine was the only actual sighting of anything, by my family.
