Organizers have planned for about 100,000 people to participate in the event, which is the precursor to the actual anniversary of the Aug. 28, 1963, march. It will be led by the Rev. Al Sharpton and King's son Martin Luther King III. On the day of the anniversary, President Barack Obama will speak from the steps of the Lincoln Memorial, from which King stood delivered his "I Have a Dream" speech.  (AP Photo/Jose Luis Magana)
