Willis is riding Old Red. They, the dogs, and sheep are at the watering trough. In the second picture, the sheep are clustered so tightly around the trough that the trough itself cannot be seen.
We know that Willis had many friends visit him at the sheep camp, some of whom we his family do not even know. If you have memories or pictures you would like to share, please contact barbaraancestorsearch@gmail.com for access to this blogsite as an author.
