So, anyway, I was finishing up this grid on May 18th, 2011 when I decided to take a break and solve today's New York Times puzzle. Lo and behold, Paula Gamache had constructed a puzzle with an almost identical theme. Almost, but not quite identical.
Ideally, the circled squares should be shaded squares. That can't be done in an Across Lite .puz file, but it can be done in a Crossword Solver .jpz file. Unfortunately, I don't have Crossword Solver, so circles it is. (You can print it out, though, and lightly shade in those three squares with a pencil to get the intended effect.)
