Loved it. Loved the grid, loved the start (KICKBALL (1A: Popular playground pastime) (A)), loved the fill, and loved the END (57D: Appropriate answer for this clue). There, I'm done. Now we can head down to Boston Common for the Womens' March!
Jeff Chen, and even Mr. Mulhern himself complained a bit about the blocky black masses in the NW and SE, but honestly, I don't mind them. If that's what it takes to make a puzzle this entertaining, then that's what it takes.
It's said that the editors initially did not want to include KINDEYES (61A: Warm, inviting facial feature) either, but I have absolutely no problem with that.
I suppose, since I'm still writing, that I might as well call out the tricky parts, like EDESSA (20A: City in Central Macedonia) (it's very confusing to have a Republic of Macedonia on its own, and a section of Greece called Central Macedonia lying just to the south, isn't it?), AVA (55D: Seat of Missouri's Douglas County), ANI (23A: Violinist Kavafian) (although I'm guessing these last two were gimmes for some), and the ever-popular-in-crosswords SEGO (46A: Bulbous perennial), but they were crossed fairly, and come on, it's Saturday! No whining!
OK, I'm going to go put on my LAPELPIN and my pink hat and head downtown.
