When you think of a farmer, you may picture an old curmudgeon in overalls and straw hat squinting out at a bucolic pasture, chewing a piece of grass as he slaps wildly at flying pests. Well, that was the old breed of farmer. Novella Carpenter is one of the new breed, and she's raising her rabbits, chickens, and goats right in the middle of Oakland. She blogs about it at Ghost Town Farm, and she just published a book: "Farm City: The Education of an Urban Farmer." KALW's Ben Trefny sat down with Novella Carpenter to ask her how exactly it all works.
