Spoiler warning for *one* clue/answer in puzzle five ahead...
Shout out to BEQ for the clue for 13A, the anonymous ACPT competitor with a great answer for it (and to Will Shortz for sharing it with the crowd), Franci for inspiring this concept with her puz from last year, and the ACPT judges for first giving me a perfect p5 score (below) and for later correcting the standings to reflect my butt-ton of errors on it (also below). Thanks to Rose for testing and being a good travel bud and roomie. And of course, thanks to Alex for making this work.
Honorable mention to Chandi, whose p5 is a sight to see.
Solve "Air Out?" here - there *may* be more than one solution to this ... good luck!
