In his newest book, "11 Days in December", master historian Stanley Weintraub transports readers to the frontlines of what was one of the deadliest battles for American forces during WWII. We'll talk about the infamous Battle of the Bulge. We'll also talk about a battlefield of a different sort here in Pennsylvania. There's a growing population of feral pigs in Pennsylvania and mounting concerns over habitat destruction and disease. Guests:Stanley Weintraub & David Wolfgang
