Black pioneers in sports

The final refrain of Martin Luther King Jr.'s most famous speech will echo around the world as bells from churches, schools and historical monuments "let freedom ring" in celebration of a powerful moment in civil rights history, 50 years ago today.

Organizers said sites in nearly every state will ring their bells at 3 p.m. their time Wednesday or at 3 p.m. EDT, the hour when King delivered his "I Have a Dream" speech in Washington on August 28, 1963.
