Just my kind of Saturday puzzle - tough! A perfect ending to the Turn (Thursday through Saturday here at H&FdtNYTcpfCA).
On my first pass through, I put in several wrong answers, including "man" (ELY (6D: England's Isle of ____), "lego" (UNIT (8D: Building block), "mazda" (ALAMO (17A: "Drive happy" sloganeer), "adrep" (CELEB (20A: One may make Us money), and probably a few others. As a result, my first real progress came in the lower half, and from there I slowly clawed my way back up.
So many answers involved a little struggle. For "26D: Golfer's approach, often," I had chipSHOT before IRONSHOT, and for "64A: Doesn't do anything rash," I began with STAYSSAfE instead of STAYSSANE. But overcoming that sort of difficulty is just what makes a good Saturday puzzle so satisfying. By the time I got back up the NW corner and finally got OCEANLINER (15A: Carnival transport) (Great hidden capital!) I let out an audible sigh of relief!
The slightly super-sized 16x15 grid allowed for lots of long horizontals. PARTNERDANCING (38A: Activity involving a leader and a follower) seems a little awkward, but FITNESSCENTERS (39A: Elliptical settings) is unawkward and very well clued. BROGRAMMER (58A: Fratty Silicon Valley techie, stereotypically) is new to me, but is amusing to learn. The intersecting "head shot" clues - 36A: Head shot (BOTOXINJECTION) and 29D: People with great head shots? (SOCCERSTARS) - make this feel a little like it was made by a "bro-structor" (doesn't work as well) but the answers are both solid. AIRPORTBAR (62A: Fitting place to order craft beer?) was a bit of a stretch though. Are they thinking that "craft" in the clue can be seen as a play on "aircraft?" Hmmm...
Overall I found this to be a challenging, but rewarding solving experience. Thumbs up!
