The first picture tells the story. This neighbor has turned his sheep onto the county road to eat the leafy spurge. It is the yellowish green looking plant in the pictures. The county can't control it with weed spray, so let the sheep loose. The second picture is part of the flock as they move down the road, grazing on the spurge, and the final picture is one of a mother and her lamb, the mother's mouth full of spurge and the lamb enjoying the day.
The Johnson Place which is the 5000 acre ranch to the south of ours is loaded with spurge. The semi's have been arriving for several days and ultimately there will be at least 3000 sheep there for the summer. Yes, in case you are wondering, we have spurge on our property also.
