Funny story to explain my absence yesterday: I got appendicitis and had surgery last night. All is well now, thankfully, and I'm recovering. So I did both yesterday's and today's puzzle this morning.
This Flag Day puzzle is early by three days. Not sure why (because no themed puzzles on a Saturday?) but it is amusing that Mr. Livegood refers to the correct date in 67A: June 14, e.g. (DATE). I like the symmetry of STARSANDSTRIPES and HAMMERANDSICKLE. The first theme entry I got, however, was RISINGSUN, and not recognizing the reference to Flag Day, because, you know, it isn't, I figured the circled letters would read "land of". No luck...
Other than the peculiarity of the timing, I thought this was a well constructed puzzle. 9D: C. S. Lewis's birthplace (BELFAST) and 43D: Tlaloc, to the Aztecs (RAINGOD) were nicely matching bits of trivia. 10A: Pen, e.g. (SWAN) was something I didn't know. I had to look it up to see why it was correct: a pen is a female swan. Similarly, I knew all the letters in 47A: Part of a round (HOLE) were right, but didn't get the golf reference for a long time. I don't like EEE, but that's the only bit of true crosswordese. Nice Wednesday.
