CRYSTAL LAKE – Hope lingered in the air Monday morning at D’Andrea Banquets and Conference Center as an assortment of speakers and performers channeled the work of Martin Luther King Jr. Speakers ranging from the Rev. Zina Jacque of Community Church of Barrington – a holder of four degrees, including a doctorate and two master’s – to Crystal Lake Elementary School District 47 eighth-grader Autumn Chase graced the stage with remarks on King’s influence and how to best implement it in modern times. Jacque spoke of seeking out others for help and advice, even if they see things differently, and to step out of one’s comfort zone in all areas of life. “I want to be really clear – rugged individualism and self-dependence is, in part, what isolates us,” Jacque said.
