Okay, of the sightings i have heard of:
Former teammate Roger was in a vehicle with two friends, who, having learned of a UL in the area stopped the car on the bridge and turned off the lights. They smelled a horrible smell like urine and rotting flesh, then something jumped on the back of the car, and they heard metal screaching. They got the car started and swerved around the curve on the other side of the bridge, and the creature toppled off the car. Upon returning to civilization, they found large clawmarks on the trunk where the metal had been rended by the claws of the creature.
Former teammate Teresa's older brother, who is in the military currently and I cannot contact him until he returns to OK, had his truck shoved off the road at night by something large, but he did not get a good look at it, as he was trying to keep his truck from being completely out of control.
Last spring Teresa reported that a fellow horserider had found a carcass of what looked to be a large rotweiler bitten in half, from the top down. by the time I was able to get a team together, the evidence was either dragged away and finished off or had washed downstream, and not recovered.
