About half way up the steps of the Lincoln Memorial is the spot where Dr. King gave his "I Have A Dream" speech. The spot is marked and I have been going there on and off this year to try to get a good shot.
The light is bad, the angle is tough and there are often people in the way.
I'll keep trying but this one is working for me.
(I included a close-up of the inscription just so you can see it).
