Seemed very easy for a Thursday. Our time would have reflected it better had we not fumbled for several minutes trying to get it accepted by the iPad app. Sure, it says things like MORT, and CORP, but it'll only take a rebus with both. Hmpf.
The trick was cool, I'll give it that. I actually changed Frannie's STUTTERED (50A: Bumbled verbally) to SPUTTERED because I had never heard of a TANSY (51D: Flowering plant). I think we also changed DUST (56D: Sign of neglect) to RUST when we put in RICERS (56A: Kitchen gadgets). It took us forever to realize that either one was possible. As I said, cool. It's really quite a thing that Mr. Gulczynski was able to work four "_ or _" words into the grid AND eight changeable answers. Impressive.
Aside from all that, though, there were several things that seemed tailored to me and my family in this one. For instance, I just took the first German course of my life mere hours before starting this puzzle, and it already helped, with 15A: Eins und zwei (DREI). We did numbers tonight, and I was able to figure it out! Thanks, puzzle, for helping with my homework! Also, my oldest brother and his family are big "Settlers of Catan" players, and he could have helped me with ORE (8D: Resource in the game Settlers of Catan). That same brother is a Reds fan, so CIN (27A: Reds, for short) made me think of him again. And STRATEGO (46A: Game with scouts and miners) went in immediately, too, because my brothers and I used to play that a lot when we were younger.
One thing I'm a little tired of, however, is OSOS (31A: Bogotá bears). That's been in a LOT recently. And I don't often spell TRANKS (69A: Downers, in brief), but when I do, I prefer the spelling "tranqs." Not that either is very good. There's plenty of crosswordsy stuff in here, but the theme is clever, and he stuck in a bunch of "semi-theme" "ors" like ORR, OER, ORE, and NOR so, let's call it a wash. Well, ok, how 'bout slightly better than that.
