This was a very impressive crossword. A lot of puzzles include phrases that begin or end with a word that fits the theme but today's puzzle included four two-word phrases---FLASHFLOOD, GASSTOP, GREENSTREET, STARSEARCH---and LIGHT could be appended to each of the eight words. And yes, I know GREENSTREET is an actor's last name but I think it still counts as a two-word phrase---especially for anyone who lives on a Green Street somewhere.
Forty black squares meant there were a lot of three- and four-letter words, and that meant that there were a lot of the usual Crosswordese words: ADO, AGE, ALEE, AOL, APE, EAT, IOTA, OGRE, TEE, USES.....and ESS, clued with "Superman's symbol." The correct answer is "S," not "ESS." Many puzzles include CEE, DEE, ESS, or VEE. Who ever decided to turn certain letters into three-letter words? I'm guessing a crossword creator came up with the idea. Does anyone know for certain? I'm sending out an ESS-O-ESS.
