Visit the N.C. Museum of History between now and Sept. 28, 2003 to get an opportunity to immerse yourself in a period you were either too high or too conservative to experience right the first time. The museum's latest exhibit, Flashback to the '60s, recalls life in the United States during a span of profound cultural change, which featured the assassination of John F. Kennedy, the civil rights marches of Dr. Martin Luther King Jr., the fight against Communist forces in Vietnam, and the rise of (and reaction against) many subcultures. Walk into the lobby of the museum and be greeted by a giant peace sign, a collection of period Barbie dolls, and the commercials and music of the period. Many of the exhibits are from North Carolina residents, from magazines collected by a Charlotte teenager to a Marine Corps uniform belonging to Raleigh's Joe A. Mobley, who enlisted in 1963. The museum is open Tuesdays through Saturdays, 9 a.m. to 5 p.m., and Sundays noon to 5 p.m. Call 715-0200 for details.
