Fifty years ago on August 23, before a crowd of more than 250,000 spectators in Washington D.C., Dr. Martin Luther King Jr., set aside his prepared speech and spoke from the heart, "...I have a dream..."
Today we celebrate King's birthday, the civil rights he lived and died for;
and the impromptu speech that inspired a nation.
Let's keep dreaming, one person can make a difference.
