That, of course, was Dr. Martin Luther King giving his “I Have a Dream” speech from the steps of the Lincoln Memorial in Washington DC in August 1963. The Martin Luther King Multi-Purpose Center in Spring Valley will be holding a “Unity Day Celebration” today at 3pm to mark the 60th anniversary of that landmark speech and the life of Dr. King at a special ceremony at Ramapo High School. While you’re there say hi to Nanuet’s Roxanne Watson, host of “Michael’s Gifts” heard here on Wednesdays.
