Laura and Dan talk with Bill Niman and Nicolette Hahn Niman, formerly of Niman Ranch, now of BN Ranch. Bill explains why pigs are the most interesting animals in the barnyard, and how a pig farmer can love an animal and still bring it to slaughter, while Nicolette discusses some of the environmental concerns specific to pigs. Then Laura and Dan learn about heritage pork and how the sausage is made when they interview Michael Yezzi of Flying Pigs Farm. Finally, Dan cooks and eats some pork butt.
