Secrets of Shangri-la bumps the White House

Due to a scheduling snafu, this program about explorers crawling through caves in a remote corner of the Himalayas will replace the "In Performance at the White House" you might see on your program guide. That show will air next Thursday after KACV's Candidates Forum. Meanwhile, the scientists in Tibet discover art, texts and artifacts from the 13th century, hidden away in extensive human carved caves created 2700 years ago to house the dead. A fascinating look at ancient cultures.
