The late Idaho Sen. Frank Church, an architect of the Clean Air Act and the Wilderness Act, is often hailed as an environmental hero. The Environmental Resource Center of Ketchum, Idaho, will pay tribute to Church's spirit at its first annual Frank Church lecture series, Dec. 4 in Sun Valley. Speakers include Assistant Secretary of the Department of the Interior Pat Shea, Idaho Statesman reporter Rocky Barker and Nez Perce Executive Councilman Jamie Pinkham. The event is supported by a grant from the Idaho Humanities Council, and is free and open to the public. For more information, contact Lee Brown at 208/726-5713 or firstname.lastname@example.org.
