This week on South Carolina Focus, we talk with Jim Knight, one of the state’s leading herpetologists, or reptile experts. He’s been studying and handling snakes, his specialty, for more than half a century, and now that summer is approaching, he says people who are out and about in the woods, on the lakes or even in their yards, may encounter a snake. Knight imparts some good advice on what to do in these unexpected meetings, and reminds us of the important role that snakes play in the cycle of nature, and perhaps even in the future treatment of some diseases as well.
