You see, keeping cattle takes a lot of work. Constant vet bills for inoculations, treatments when they get sick. Corn-feeding, to maximize their size, means buying a lot of corn. Constant attention and work. And my parents' friend, well, he was tired of it.
So he put his cattle out into a field. And he did nothing. If one got sick, it went to the dog food place. They ate grass that grew in the field. They didn't get as big and he didn't make as much money, but he also got to take things a bit slower, easier.
Then, organic beef became a big deal. He did not give a shit about 'organic' or whatever these strange hippies were talking about. But he was more than happy if they wanted to pay him extra for his laziness.
(Note: I am paraphrasing a second-hand story and while I grew up rural, I didn't raise cattle- mistakes are being made here, forgive me.)
