An Ostrich-Horse?
On January the 8th of 2000, the witness went to a gun show wearing a bigfoot-themed t-shirt with the intention of talking about said cryptid with the various outdoorsmen and hunters who would attend the event. He met one vendor who owned an outdoor goods booth, and who told him a strange story about what appears to be a hitherto-unknown creature - both to science and cryptozoology.
The vendor apparently travels a lot, and he decided to pull over to the side of the road on one of his long trips in order to sleep ‘as he often does’. He parked up near the cemetery of Ripley, Oklahoma - but made a point to tell the person who later recounted his story that he has done this multiple times before and ‘it has nothing to do with the story except to tell the exact location’.
He had only just laid down to sleep when he heard a strange noise and immediately sat up in his seat to look out of the window. Just as he did this, something ‘ran in front of the car making a loud noise’. It had the shape and size of an ostrich, and the he thought that was what it might be ‘until he looked at the head’. The head resembled that of a horse - not exactly, but ‘that was the general shape’. When he was asked to describe the noises that it made, he struggled to put it into words but managed to say that it was ‘very loud and aggressive sounding’. Presumably alarmed, the witness stuck his revolver in his waistband and sat still for a couple of minutes, before wisely deciding to find another place to sleep.
The creature described in this account sounds a lot like the Jersey Devil of New Jersey folklore, but lacks the bat-like wings often associated with the creature. It makes me wonder if perhaps the Jersey Devil reports were based on confused sightings of multiple creatures - perhaps one of these ostrich-like entities and a pterosaur or dragon-style being in the same area?
