Anyway, I'm not starting this post until almost 10:00, and I'm not sure how much more I have in me.
After an initial run-through, I had about six answers filled in. 20A: Dutch export (Edam), 44A: Having good balance (sane), 45A: Target of milk of magnesia (acid), 28D: "A Prairie Home Companion" co-star, 2006 (Streep), and 38D: Big name in ergonomic utensils (Oxo). Nope (47A, clued as Informal demurral)...that's only five. The X gave way to 43A: Little tricksters (pixies), and one thing led to another.
I had two very good (very wrong) long answers. 28A: Swear words? I had So help me, God...isn't that what you say when you're sworn in? That should have been Scout's honor. I was a little closer with 37A: Scheduled (on the docket). I had on the roster...trying to make a sports clue out of it, I guess.
Some of the long answers were so good I'm still shaking my head. How does he do this?
8D: Where many prints may be found (crime scenes). While not a gimme, that one came together fairly easily. I headed right to forensics, rather than to the art museum.
24D: Abscissa (X coordinate). Okay, I'll admit I had to look up abscissa. I had no clue what it meant...I kept thinking about an abscessed tooth. Gross.
Liked the connection between 16A: "Great taste since 1905" sloganeer (RC Cola) and 35D: 16-Across, e.g. (soda pop). We've had the RC clue before, and I'm sorry to say it took too long for me to get it this time.
My absolute favorite answer in the puzzle...the one that drove me absolutely crazy until I had it...was 17A: Rule broken in leisure? (I before E). I knew I had everything right up there, but nothing was going to end in FOREE. Well, it would if you parsed it correctly. Once I got that, the rest of that corner fell into place. I would never have guessed 1D: Totally unemotional type (icicle)...I wanted something that began with UN or IN.
2D: Wheels (nabobs) was another area of confusion for me. I don't normally think of important people when I hear the word wheel. Maybe I should...at least where puzzles are involved.
Have never heard of 44D: Flying predators of cold seas (skuas), but I was able to get it from the crosses.
I always like to learn new colors so was very happy to see 40D: Shade deeper than heliotrope (indigo)...one of the colors of the rainbow. Here's another Hawaii photo...Somewhere Over the Rainbow. If you haven't heard Israel "IZ" Kamakawiwo'ole perform the song, check it out. He's way popular in Hawaii. By the way, if you click to enlarge this photo, you'll actually see a double rainbow.
Other multiword answers (which I love) include 1A: Stuck (in a spot), 8A: "Not possible (can't be), 14A: It might go off during a 30-Across (car alarm), 51A: Tax burden? (IRS audit), 53A: It might go 7-5 (one set), 54A: Thing with a pressure point? (oil gauge), 7D: Kids' hideaway (tree fort), 32D: Fruit found among needles (pine cone), 34D: Battle of Put-in-Bay setting (Lake Erie)...the list just goes on. Any wonder why I love Mike's puzzles?
Repeated cluing (__ dog) appears at 19A (Coney) and 52D (sly). I got the second one right away, but I wanted salty for the first.
41D: Sonnet section (sestet) refers to the final six lines of a Petrarchan sonnet, which brings us to the WOTD, sextet...a group of six persons or things.
It's way past my bedtime, but I didn't give the puzzle short shrift after all. Here's the grid...
...and I'll see you tomorrow.
