A Purple State of MindOn this edition of Charlotte Talks, we meet former college roommates from Davidson College who met in 1985. It was the first year as a person of faith for one roommate, the last year for the other - this produced many discussions and arguments their sophomore year. After college, they lost touch and when they found each other years later, they never talked about those discussions until filming their documentary, "A Purple State of Mind." A conversation about faith, politics and lessons learned on Charlotte Talks. Guests:Craig Detweiler John MarksMore information about the film: www.purplestateofmind.com.
