The puzzle's theme answers offer a parade of animal-inspired (?) locomotions from FROGMARCH to GOOSESTEP. I guess my favorite is TURKEYTROT, although, we are getting a lot of turkeys 'round these parts lately and trot is an overstatement when you are waiting for them to get out of the way. Turkey amble is more like it. Of course, the answer was referring to an old ragtime dance, not the pace of an actual turkey, but it made me think of it. For some reason, I tried to come up with other entries. Would pussy foot work?
There were a number of additional theme work horses, so to speak, including Hogwash (LIES), Swine (BOARS), and Young raptor (EAGLET), not to mention Operating smoothly, as an engine (PURRING).
Frannie's Grid Goodies (TM) [sorry!] for today are TOUSLE, LOGE, ALFALFA, BARRIOS, and LEISURE. I enjoyed the clue at 51D. "Coverage of senators in ancient Rome?" (TOGAS) and "Bad thing to have on one's face" (EGG). I thought 31D, "One of two in 'Waiting for Godot'" was especially nice because the play has two characters (Vladimir and Estragon) in addition to two ACTs.
Less ADMIRED by me were ABACI, SOUTHER, and SRA. I thought "Trickled" as a clue for OOZED was less than perfectly apt. ASP! I also think constructors should say goodbye to ELLO.
