AS IT WERE
The theme today is the past tense. It was overly ambitious, it seems, to try to turn such an inactive topic into an engaging hook. The porch crew (Frannie, ET59, and me) found this one a little too easy and a little too flat. The last square for all of us was the guess of "S" at the cross of ENSOR (49D: Newsman David) (Why not use the Belgian artist?) and GSA (62A: Fed. property agency) ("General Services Association"). ALAS.
We were all slightly surprised by GALILEO (109A: "Two New Sciences" author), as the title led us to expect a more modern author.
Is it weird that BREAKGROUND (122A: *Start of a construction project) is made up of a present tense verb and a past tense verb? And I suppose "Power," "Dog," and even "Kid" could be taken last present tense verbs, too. But that's getting a little too picky, maybe. But then, there's names like DORS, and KNUT, and ESAI, and fill like HBAR, ENNA, and ASES. Overall, meh.
