Well, Dear Readers, this Wednesday's child is full of FWOE. I blithely entered 'fOCI' for "Centers of activity" instead of LOCI. That left me with the SUfFA instead of the correct SULFA for 50D: "Bacteria-inhibiting drug" - which proved fatal to a clean solve. :(
While that was my only actual error, there wasn't much about my experience today to CROW about. Even with such gimmies as ALLS "'fair in love and war'", "Cry between 'ready' and 'go'" (SET), NULL "and void", and "Gertrude who wrote 'Rose is a rose is a rose ..." (STEIN), the whole solve felt slower than it seemed like it should have.
All that being said, I did enjoy puzzle, including the entertaining theme that offered a set of answers (BADINVESTMENTS, ONEWAYTRIPS, SERVICESACES) that would allow one to say, with APT, SORRYNORETURNS.
There were many clever clues in the puzzle - one of which duped me: "Shortest month of the year" (MAY). It took me a few to get past the more obvious but incorrect 'feb'. I also liked the delightful ambiguity of "Is down with" for HAS, "Large number" for HOST, and "Draft choices" for ALES.
On the flip side, there were a number of good QMCs that did not trick me - this time - including "Accumulating bank deposits?" SILTS and "Head of a brewery?" FOAM. I especially liked ATTIC for "Website?" Also, TIS "but a scratch" - LOL.
I have yet to encounter anything that literally fits the description, IDIOTPROOF. The search continues.
