It was far too fast to be a human.
The teller and a friend visit an older man a couple of times a month. He lives alone in an old farmhouse on a big piece of land in southern Ohio, about as far from anything as you can get in that state, and he loves driving his golf cart along the trails through his woods. When they visit, they clear any fallen trees off those trails for him.
A few weeks before the post, he told them he had stopped going out on the cart. He was frightened. Far at the back of the property stands an old one-room schoolhouse, abandoned for decades, with boarded windows and half its roof caved in. He said someone was living in it. He'd seen a man dressed all in black hiding behind the trees near it, and the boards over the doorway had been torn off.
The two friends offered to take a look. The teller privately assumed the board had simply rotted off and the old man had mistaken a shadow for a person. Hardly anyone would even know the building was there.
It was nearly dark by the time they walked the half mile back to it. Something had clearly been using the place. Saplings were pushed over, a trail had been worn through the weeds, and the boards were ripped away from the door and one window, with broken pieces still lying on the ground.
Then they heard movement inside. The teller ran to the doorway, the friend right behind, and shone a flashlight in. Something the size of a large man, covered in long dark brown or black hair, shot across the far side of the room on two legs and stepped straight out through the open window.
They ran around the corner of the building after it. It stopped for a moment at the edge of the trees and looked back at them. Its eyes gave back a faint orange shine in the flashlight. Then it was gone into the woods, astonishingly fast and almost silent.
The next day they put up three trail cameras around the schoolhouse. When they collected them, one had been twisted around its tree to face away from the building, and it had taken no pictures at all. The other two caught only ordinary woodland animals.
Both friends are experienced outdoorsmen who have seen every animal Ohio has. The teller has watched bears stand up on their hind legs and says this was not a bear. It was too fast to be a person, and its body was built differently. They don't believe in Bigfoot, and they point out that what they saw doesn't even match the usual description. It was slimmer, without the broad shoulders, and its head looked small for its body. They just can't explain it.
