Today we remember that sixty years ago, Dr. Martin Luther King Jr. gave his “I Have a Dream” speech at the "March on Washington for Jobs and Freedom." Celebrated as one of the greatest -- if not the greatest -- speeches of the 20th century, and carried live by television across the nation, I still find it hard to imagine what it must have felt like being there, listening to Dr. King's voice, along with more than 250,000 non-violent protesters.
