"On today's edition of Dakota Midday, host Paul Guggenheimer welcomed David Mancini and Avalon Kann, Director and star of the University of South Dakota's production of ""Doubt: A Parable."" The play examines how far one will go for their beliefs without any proof. Then Paul spoke with Karlene Hunter and Mark Tilsen of Native American Natural Foods makers of the Tanka Bar. They were invited guests at the White House last week when President Obama announced plans for helping small business owners through the worsening credit crisis. And finally, Paul interviewed Dr. Alan Robock, professor of climatology at Rutgers University. He's presenting lectures on global warming and community involvement at South Dakota State University on Monday."
