TV star Jeff Corwin brought a portion of his Animal Planet channel show to Humphrey Coliseum recently. The internationally recognized wildlife habitat conservationist was the first speaker for the Dorothy Garrett Martin Lecturship in Values and Ethics sponsored by Delta Gamma social sorority. His discussion of a 12-foot, 40-pound Burmese python left audience volunteer Lindsey Foreman especially breathless. The Duck Hill freshman was among more than 3,000 attending the program.
