Once relatively powerless positions, the roles of governor (and first spouse) have evolved dramatically over time. An exhibit at the North Carolina Museum of History in Raleigh explores more than 200 years of gubernatorial history, featuring portraits, photographs and personal clothing as well as artifacts ranging from an inkwell that Gov. Zebulon Vance used during the Civil War to fragments of Apollo 11 moon rocks presented to Gov. Bob Scott in 1969. Visitors also learn about First Lady contributions such as Dottie Martin’s Wildflower Program, a highway beautification program that continues today. There’s also a special section on campaigns and voting practices. “Leading the State: North Carolina’s Governors” runs through Sunday, April 28.
