Smithsonian Institution Secretary G. Wayne Clough and Agriculture Secretary Tom Vilsack walk from the U.S. Department of Agriculture Whitten Building across to the 2012 Smithsonian Folklife Festival, on the National Mall in Washington, D.C. on Friday, June 29, 2012. One of the three themes this year is “Campus and Community.” It celebrates the 150 years of the USDA and the Land-Grant University System. The U.S. Department of Agriculture (USDA) and the Land-Grant system extend education across the country, contributing to American agriculture success and rural prosperity. “Campus and Community” has demonstrations, discussions, hands-on activities, and entertainment to that showcase the many ways that this partnership works to improve American agriculture and rural life.
