On September 6, the Los Angeles Times will introduce a Sunday version of the daily crossword by David Poole. Today, August 30, Merl Reagle's final crossword appeared. During the past week, the Times published several letters from fans of Reagle's puzzles. One man had a unique approach: He tried to fill in only the theme answers. What a challenge! I doubt that any of us could come up with all the clever wordplay that Reagle came up with. He will definitely be missed.
