(10/09/09) Historian Zoe Trodd gives a lecture Saturday afternoon in Lake Placid to mark the 150th anniversary of John Brown's legendary raid at Harpers Ferry, Virginia. That raid struck a blow against slavery. Trodd will talk about the North Country's most famous abolitionist at the John Brown State Historic Site at 2 pm. Her talk kicks off a series of commemorative events this fall that will include a symposium and a reenactment of the return of Brown's body to North Elba. Trodd describes herself as modern-day abolitionist who takes inspiration from John Brown for today's movement against slavery and human trafficking. Todd Moe asked her how Brown is still relevant 150 years after his death.
