Wicca or Neo-paganism began as a movement to recreate pre-Christian nature religions. It turns out to be just what a lot of scientists are looking for. Anne Strainchamps prepared this report on the growing popularity of Wicca. We hear from Ronald Hutton, a historian of paganism and author of "Triumph of the Moon," and from Margot Adler, NPR's New York Bureau Chief and author of "Drawing Down the Moon." We also hear from Wicca practitioners in Wisconsin and Scotland.
