The four theme answers are spooky alternate spellings of familiar phrases.
20A: Scary sound from the ocean? (humpback wail).
28A: Scary sound from a war zone? (battle creak).
37A: Scary sound from a cornfield? (farm groan).
50A: Scary sound from a steeple? (bell and howl).
I thought this was a clever little theme...and the puzzle a little tougher than normal for a Tuesday.
Went completely blank on 10A: TV horse introduced in 1955...or a Plymouth model introduced in 1956. I thought Mr. Ed was later than 1955, and I didn't remember that Plymouth made a Mr. Ed. Maybe it's just that I'm tired, but it took too long to remember Fury...who I always confuse with Flicka.
Other spots that tripped me up:
53A: Tedious (prosy). Don't think I've ever used the word. It kind of reminds me of leprosy...probably because I read about Father Damien and the lepers on Molokai.
63A: African antelope (eland). Here's a picture for those of you who didn't know about them.
70A: Card game for three (Skat). Haven't ever played it. Actually, I don't think I've even heard of it...but I liked its cross with 54D: Sport utilizing a clay disk (skeet).
21A: Country just south of Sicily (Malta). Because I'm geographically impaired, I had to rely on crosses for this one, although I managed to guess pretty early on. For the same reason, I struggled briefly with 43D: Neighbor of Slovenia (Croatia). Again, a couple of letters made it happen.
40D: Egyptian dry measure equal to about five-and-a-half bushels (ardeb). I don't feel too bad about not knowing this one...Don didn't either. Here's everything you ever wanted to know about an ardeb but were afraid to ask.
52D: Musically improvise (noodle). I still can't remember the word I thought was the answer, but I haven't heard or used this expression.
34A: Kodiak native (Aleut) was in the puzzle fairly recently. Another gimme because of a recent appearance...33A: Juillet's season (ete). Unfortunately, I don't get the clue, but I knew it was what they wanted.
Favorite clues include 11D: Helpless? (unaided) and 22D: Moo goo gai pan pan (wok).
Best answers in the puzzle include 3D: Cane cutter (machete), 12D: Filled to the gills (replete), 42D: Tag for a particular purpose (earmark), and 46D: Co. addresses, often (PO boxes).
Least favorite answer...45A: Sales slips: Abbr. (rcpts). I understand that sometimes things like this have to happen in construction. I'm just sayin'.
Yesterday I mentioned the difficulty with AVER/AVOW. Today we have the same kind of problem with 30D: Fit for a king (regal)...could have just as easily been royal.
And I would be remiss in my aloha duties if I didn't point out 61D: Island with Waimea Bay (Oahu). It wasn't my favorite island...much too crowded...but it's still Hawaii. And here we are at the top of Diamond Head, taken on our first trip two years ago.
After doing puzzles for a while, I've finally learned not to automatically put an S at the end of a plural answer. 58D: Hospital shipments (sera) was a gimme.
Time to call it a night. I'm still beat from consecutive late nights.
Here's the grid...
...and I'll see you tomorrow.
