The mid-season finale of AMC’s "The Walking Dead" airs this Sunday. For eight seasons, Rick Grimes and his team of zombie hunters have been trying to protect humanity from those ravenous, undead monsters. The show is filmed here in Georgia, and the characters are only one part of the show’s success. Another big part: the props. "On Second Thought" regular Kalena Boller caught up with Danny Gorbachov, a props assistant on "The Walking Dead."
