The whole process was a great experience. From the period of apartheid to the present era. I suggest that friends go to the Atlanta History Center first, then visit the Civil War Exhibition, and then come back here. The schedule is very good. As you all said, Woolworth lunch counter is not to be missed. Close your eyes and do it with your heart. It's very touching emotionally. The double-edged sword of technology and how to interweave the liberation and abuse of human rights is a good debate.
