If you’re unfamiliar with the show The Walking Dead, zombies (called "walkers" in the show universe) have taken over the landscape. Our cast of gun-toting survivors have been left holed up in a suburban compound surrounded by large walls.
This week, two main characters venture outside the compound on a scavenging mission equipped with a map to nearby agricultural supply stores. Before they leave, a third character tells them to keep an eye out for sorghum. He says it will likely be untouched and it would make their farming situation “hunky dunky.”
A quick glance at Twitter and a few text messages from friends and family all asked me the same question: What is sorghum and why do our post-apocalyptic heroes -- and sometimes anti-heroes -- need it?
