Vermont Public's Betty Smith celebrates 50 years in public radio

Betty Smith is known as Vermont Public’s founding mother. She’s been with the station since its very first day, and this year, she celebrates her 50th anniversary in public radio. She’ll tell us stories from the early days of VPR, when they weren’t sure the station would survive, and her thoughts on public media's future. Then: a new film about the melting ice of Greenland features a University of Vermont professor.
