Playing the part of "out with the old" we have NYE ("12/31") in one corner, and for in with the new, we have the numbers 2021 smack dab in the middle of the puzzle. The number grouping itself is not clued, as Horace pointed out. Instead, four answers contribute numerals to form the celebratory block. Although, another feature of the advance of the years reminds me that FOREVER21, I am definitely not. I also appreciated SOLASTYEAR. I hope to apply that term to many aspects of 2020.
Overall, I enjoyed the puzzle and, for a Friday, solved it pretty quickly. My first time through, though, I thought I was going to have trouble, but as it happened, I knew a few answers in key areas including QUEEREYE, DREVIL, AUDEN, TWOSTEP, and then I POLEDANCED my way through the rest of the puzzle to a successful solve.
Some highlights include UNPERSON and EDITSOUT, a nice, if troubling pair in the northeast. ASTUTE and OBTUSE are also nice. ERRS for "Chokes" took me a minute, but I appreciated the clue once I figured it out. Alternatively, ARESO for "It's true" seemed less apt.
There were some fun QMC's to REVEL in. "Complete a lap?" (SIT) was funny. "TV sets?" (SEASONS) was another good one, as were "Do one's part?" (ACT) and "Special gift, for short" (ESP). But my favorite C/AP today was the non-QMC "More than most" (ALL) - ha!
It seems, dear Readers, like a good moment to pause and appreciate the PAGEANT of word play that puzzle constructors create and that provide us with so much entertainment, especially during the rather bleak preceding 366. IFORONE hope 2021 is at least 20PERCENT better than 2020. Happy New Year everyone!
