Account

On a fall evening just before dusk, the witness, then a child, and the father were at their farm when the father heard a loud disturbance in a wooded valley below a field. The father took a tape recorder and walked toward the sounds of a loud growling/roaring creature apparently fighting a neighbor's dog while the child waited uphill by a feed trough. The creature was never seen because it was too dark in the woods, and the father returned uphill. The neighbor's dog was never seen again.
