It's been a long winter, and I'll take any hopeful thing I can get, so today's theme was perfect. INBUD (49D: About to bloom … or a hint to 20-, 33-, 41- and 52-Across) meant that all four theme answers were "wrapped" in the word "BUD." BURMAROAD (33A: Allied supply route to China during W.W. II), for example.
The rest of the fill was decent. Some clever cluing, like 6D: Flaming felony (ARSON) and 39D: Volume that requires lots of preparations to complete? (COOKBOOK) were both pretty good. And I like the uncommon BUSS (33D: Smooch), the French angle (somewhat common) in SEINE (12D: What the Left Bank is a bank of) and BERET (43A: Tête topper).
As usual, we see ANIL and OBIS, and the unknown (to me) ILIA (38A: Olympic skating champ Kulik), but overall, this was a fine Tuesday.
