My Grandpa is 73 years old, and one thing I would know about him, is that he would never tell a lie.
My Grandpa's Grandpa owned a farm in South Dakota (where he is from), and just a little ways from his farm, was a bar, and you had to walk about a mile on a dirt path to get there. Now in my Grandpa's time, teenagers (my Grandpa was, at the time, 15) could go into a small town bar at any time, whenever they wanted, because they needed the business.
So at about 9:00 p.m. In the summer time, my Grandpa and his brother, Warren, went out to the bar to shoot pool (they did not have a drop of alcohol), and once they were done, it was about 11:30 p.m. They were walking slowly (Warren was on crutches) and talking to each other when Warren noticed something.
They noticed a tall, black figure walking, and stepping when they stepped, parallel to my Grandpa's feet. My Grandpa threw rocks at it, but nothing happened, as it seemed, the rocks would go right through this figure.
My Grandpa, scared, ran as fast as he could, but forgot Warren behind him, and the figure disappeared. They hurried to their Grandpa's farm, going as fast as they could and eventually got there around 12:30 a.m. Now this is where it gets really eerie.
When my Grandpa got in the house, he locked the door behind him. But as they were trying to imagine what was that thing, something was tugging on the door. Their Grandpa, fast as wind, went to the door with a gun in his hand. But as he opened the door, nothing was there.
Tomorrow morning, they found SMALL footprints EXACTLY where my Grandpa saw this figure, which is abnormal for how tall this thing was. Oddly enough, there wasn't any footprints next, or in front of the house.
Their house was in the middle of nowhere. There was not anyone at the bar except the manager, who was short, and was there when they left, and themselves. And that was the only thing in circumference to their farm; it was an extremely low chance that a human could've been there that fateful night.
