I was deeply moved to see that sea of humanity. Individuals wanted to get as close to the Lincoln Memorial as possible, but it was impossible because there were so many people. Back in 1963, there were more trees on the [National] Mall. And many of the young men, black and white, got up in the trees to get a better view of the podium. And when I got there, and I turned and looked back, it was just amazing to see the crowd.
