An unidentified "Freedom Rider" sticks his head out of a chartered bus window in Jackson, Miss., having arrived from New York, Aug. 14, 1961. These black and white Riders were testing a Supreme Court ruling banning racial segregation on interstate public transportation. Vanderbilt University has invited college students to take a bus ride to retrace the 1961 Freedom Rides with several of the original participants. The idea is to discuss the significance of the rides and what needs to be done to further combat racism. (AP Photo)
