Participants gather at the base of the walk up trail to commemorate the life of Dr. Martin Luther King, Jr., by climbing to the top of Stone Mountain with children who aspire to be great during "The Dream Walk" on Sunday, Jan. 17, 2016, in Stone Mountain. In his "I Have A Dream" speech, Dr. King spoke of a symbolic bell of freedom ringing from the tops of Stone Mountain to the hills of Tennessee. Curtis Compton / ccompton@ajc.com
