Well, this was a whole bunch of fun. I solved it with Cece and her friend Grace (age 13 and 12 respectively). Cece got WHYYES, and Grace got GLIMPSES, so definite input from the young 'uns.
We broke into the grid at 28A: Man's do with upswept hair in the front (QUIFF), and discovered the string of 3 Qs. I wanted QUAKES at 24A: Trembles (QUAILS), but got it at 28D: Country rockers? instead. That's a cute little clue. Having filled in that little section of Qs, WETSUITS got us into the NW. As some of our readers know, I don't love grids which have such slight entries from one section to another. It means that the corners become separate puzzles.
That being said, I thought the NW corner was really top drawer, to quote a favorite film. I'll dispense with the theme of the month right here: 1A: Shop class cutter (BANDSAW) gets an A- from me. Partly that's because I misinterpreted the clue to mean exactly what 8A: Class cutter, say (SLACKER) meant. I love that we get both meanings across the top like that.
Meanwhile, you also get AVERAGE and LEGOSET, both with good clues. And 23A: Social group (ANTS) is a lovely little clue for a common word. Nice corner!
FROZEN got us into the eastern half of the puzzle. Cece suggested "moos" for 30D: Stock exchange? (LOWS), which put us off for a little while there. Other than PLANA which merited a collective "Huh?", the NE has some lovely entries as well. The trio of KAMIKAZE, EXAMINES, and RELAXANT are so rich in high-value Scrabble tiles. And ABYSMAL is great as well.
The rest of the puzzle moved pretty well along. FAXES crossing ZAXES looks great. Overall, the puzzle has three Qs, three Xs, three Js, three Ks, and three Zs. That's equal access letterage!
Meanwhile, 55D: Important Peruvian crop (OCA) gets our last entry of the puzzle. I'd never heard of it before and just trusted my acrosses. For the education, it gets a B-.
Happy lead-in to a long weekend.
