Even the most casual cable TV viewers have, on occasion, been led to ask themselves "How long could I survive in the wild without food? What could I eat?" Peter Carrington will offer those kind of insights tomorrow at Michigan State University’s Beal Botanical Garden. He's the assistant curator of the Beal Garden, where he is the edible and toxic plant specialist. He’s also been an assistant instructor in the MSU plant biology department. His free, 40-minute session is called "Weeds you can eat, and NOT."
