For a Monday puzzle, this had some tough ones. The fairly easy crosses brought it back to a Monday level.
While much of the country has been dealing with winter storms, it was nice to have a change of seasons today.
17A: Upstate New York city and spa (Saratoga Springs).
24A: Honeymooners' destination (Niagara Falls). My parents went there for their honeymoon in 1948...they were married in Hartford, so it wasn't a long trip. I've never known anyone else who went there, but it looks beautiful.
42A: Former president of Harvard (Larry Summers).
54A: Comic who played Robin Williams's son in "Mork & Mindy" (Jonathan Winters). I totally forgot that...but once I read the clue, I could see him in my mind. I wasn't able to find a picture of him in that role...picture him in shorts on a trike.
The tough stuff:
14A: Elementary particle (muon). I know very little about any of the sciences. When I had all of the crosses, Don confirmed the answer. I don't know how he remembers things like that.
13D: Swiss city on the Rhine, old-style (Basle). Never heard of it.
18D: Dwellers along the Volga (Tatars). Or them.
19D: Working stiff (prole). Proletariat, sure. Prole, no. According to my dictionary, it's somewhat derogatory.
23D: French city where Jules Verne was born (Nantes).
Multiword answers worth noting including 9A: Lesser-played half of a 45 (Side B)...the clue's too easy, even for a Monday, 56A: Auto route from Me. to Fla. (U. S. One)...we made that trip many times before the interstates, 58A: Smell __ (be suspicious) (a rat), 5D: Shipment to a steel miller (iron ore)...a little tough when I couldn't remember the appropriate letter for 5A: Letter-shaped structural piece (I-bar), 10D: Isle of Man's locale (Irish Sea), and 31D: Time before talkies (silent era).
Favorite answers include 50A: Mythical island that sank into the sea (Atlantis), 61A: Without: Fr. (sans)...one of the few French words I know, 3D: Homeowners' burdens (mortgages), 4D: Like clocks with hands (analog), 9D: Spread out ungracefully (sprawl), 27D: Passionate (fiery), 35D: Broad-minded (tolerant), 37D: Pago Pago resident (Samoan), 43D: Mountain ridges (aretes)...a recurring answer, and 40D: Besmirches (sullies)...love both the clue and the answer.
My favorite clue...44D: Powerful rays for mantas.
That's it for tonight. Here's the grid...
...and I'll see you tomorrow.
