Arthur Grant and Nessie.

Via: modern mechanix

"In one of the first sighting of the creature out of the water, Arthur Grant was riding his motorbike back to his house in 1934, when he nearly ran into a creature crossing the road. In the light of the moon he could see a long necked animal with a small head, thick body and a long tapering tail. The creature seemed to be moving by the aid of flippers protruding from its body. The creature went back down to the loch, and disappeared into the water and out of his sight. "
