OMG. Let's consider first of all the clue 24D: Summer symbol? You see that and you think of flowers and birds, and maybe beach-related items, and eventually, when you get five or six crosses that you feel good about, you realize that the answer is PLUSSIGN. It is then that you realize you are solving a puzzle created by a different... a deviant mind. Another example might be "9D: Reagan was seen a lot in them." You think of movies, articles of clothing, newsreels, but the answer is EIGHTIES.
This puzzle was devilish. PREEMPTED (32D: Broken into on TV?) is another crazy-looking answer. We had _REE... for a while and all we could think of was "Free" something. The divided double-E is genius.
We were looking for tricky clues from the get-go. Franny plunked down BALLERINAS (26A: Ones keeping on their toes?) without crosses, and I did the same with ONIONRINGS (17A: Circular side?), but others took almost every cross and then some. The toughest intersection might have been IRIS (55A: Color also known as endive blue) (really? By whom?) and PROSES (43D: Talks tediously). That's not a definition for "prose" that I was aware of, but it is the seventh entry for the word in my Random House, so, well, ok then. I'm not up on my tiny units of measure, either, so MIL (57D: 254,000 angstroms) took two crosses and a guess.
All my complaining aside, however, this is what we expect and, indeed, want from Friday and Saturday puzzles - a struggle. Thanks, Dana Motley, for an hour and a half of challenging enjoyment.
