My grandfather raised sheep for the wool. Raising the sheep was something he and my grandmother took on after my grandfather retired. They liked the animals and thought caring for them would be fun and a good way to remain active as they aged.
The new hobby/occupation proved to be great for my grandparents. They loved the animals and they met other people who were in the sheep business as well. Each year the sheep farmers would host workers from Australia who came to the U.S. to shear sheep. The workers would work at all the sheep farms in the area and then move across the country working at other farms and earning money as they went. For the workers, this was an annual trek.
