Decided to revisit the grid style from a few weeks ago for today's puzzle. No surprises that with a grid like this, with all the long answers intersecting in the middle, the seed answer is going to be one of those. Little fun fact, I'd wanted to use the clue for 15-Down (at least conceptually) for a totally diferent answer in a puzzle I made a few years ago. But to be frank, that clue/answer pairing just didn't quite work for the older puzzle, so I didn't use it. Whereas today it's right on the money. So the moral is: save those shaky clues/answers because eventually you can use them. Enjoy.
Share the puzzle. New one on Thursday.
