Today is the 54th anniversary of the Greensboro sit-ins. As a local television station describes it:

On Feb. 1, 1960, four black students at N.C. A&T sat down at the segregated lunch counter at the F.W. Woolworth store in downtown Greensboro and demanded service. The protest continued until July, when the counter was desegregated.
