Many of us enjoyed SCALENE (21A: Like the figure formed by the three circled letters in the upper left) when it appeared just two days ago, and I'm sure we'll all like it again today. It did, however, immediately give away the theme and the other two centrally-located longish theme answers, ISOSCELES and EQUILATERAL. And, to be thorough, the circled letters spell out TRIANGLES. It was an unusual theme, and I have no idea how hard it is to place circles with specific letters, but the fill in this one seemed on the high side, so either Mr. Raymon is very good at what he does, or it's not that hard. Let's be charitable and go with the first option.
It started with a couple of partials on the first line, ATAB (1A: Run up ____) and OHTO (10A: "____ be in England") (ironically, the first one was the harder of the two for me to get), and then we quickly see such junk as TMEN and ARIS, and it ends with a dreaded "en-" word, although ENSNARE (68A: Sucker in) is, admittedly, one of the better ones. But the long downs make up for it, in my opinion. ANTWERP (1D: Belgian seaport) (Hey, did I mention that we were recently in Belgium?), is nice to see, and who doesn't enjoy any reference to "Stephen Colbert's 'I Am ____ (And So Can You!)?" (AMERICA)? HERONRY (11D: Nesting area for wading birds) checks out in the ol' Random House College Dictionary that I keep on the desk, but damn if it didn't take me forever to come up with those last two letters! By contrast, TRISTAN (12D: Isolde's beloved) went in off the T, and I didn't really even need that. I just had it.
It wasn't without it's problems, but overall, I'd say this was an enjoyable, if slightly quick, Wednesday puzzle.
