I was deeply saddened to learn this morning that the iconic folksinger and civil rights/environmental activist Pete Seeger died at 94. What a life of contribution! The New York Times obituary ended with a most fitting remark: "Through the years, Mr. Seeger remained determinedly optimistic. 'The key to the future of the world,' he said in 1994, 'is finding the optimistic stories and letting them be known.' "
