Wow, this was an odd Tuesday, wasn't it? Four symmetrical blocks of units of measurement - inch, foot, yard, mile - that increase in order from smallest to largest. They are what the crossword folks like to call "triple-checked." That is, each one of the four letters (and it's kind of cool that each one is four letters long, isn't it?) is included in three different words. And when that happens, things like NIIHAU and ABSEIL (Descent by rope, as in mountaineering) often happen too. I'll admit, when I entered each of those two I feared I was making a FALSESTEP, but in the end they were right!
But they're not bad, really, because they're actual things, and that's fine. In addition, we've got the exotic IGUANODON (Bulky herbivorous dinosaur), the always amusing BEDHEAD (State of one's hair after a night's sleep), and the stately CONCHS (Seashells used as trumpets). And I liked all the answers including single letters - GOTANF (Flunked), ONEG (Universal donor's blood type, informally), HIGHCS (Notes reachable by sopranos), and TGEL (Neutrogena dandruff shampoo). OK, that last one isn't so great, because it's a product that I've never heard of, but it fits my theme. Speaking of products, one that I can get behind is RONCO (Company behind the Veg-O-Matic). I've never bought anything from them, but the name always brings a smile.
The next step up, I suppose, is answers featuring two-letter pieces, like HOLDEM, MRHYDE, CDROM, and the slightly duplicative GOFOR and ILLGO, and FEDON and LAYON. (See also BRINGITON, ONION, and the aforementioned IGUANODON.) :)
Things got a little name-heavy in the NE (TOBY, LIN, ANG, URIEL, YSL, TESLA, ORKIN), which can be a little DRAB, but in other places we have the fun word (although not always fun for everyone) EDICT (Decree), the descriptive DEFANG (Render harmless), and the tasty DESSERT (Part of the meal that the British call "afters").
Overall, I think this is a pretty impressive Tuesday. It gets a SMILEY from me.
