Rather easy, but had a little problem with 11D. Of course Harper's is published in NY. That ethnic group contributes all manner of wonderful expressions to English. Too bad "bupkes" wasn't in there.
My faves: A - 15, 34, 45, D - 4, 30.
Minor quibble with 24D - the first "in". Seems superfluous, but the surface read would suffer without it. Perhaps I'm parsing incorrectly.
