The answer: renting out a minihouse through Airbnb
Another piece in the media suggesting comfort animals, as in those with big brown eyes, aka "cows", is the answer.
The real answers, of course, are:
- off-farm income, as has been the case for decades.
- drawing down capital (i.e., the value of land and buildings) (My mother used to fuss about farmers who would be better off selling out and investing the proceeds in bonds.)
