Likely, not too many recognize this song sung many years ago by Hoagy Carmichael. (See link below) It was nominated for an Academy Award in 1947. Me? I was 11 at the time. I think my photo for today is a 'buttermilk sky' (also called a 'mackerel sky).

(Wikipedia) - "A mackerel sky is a common term for clouds made up of rows of cirrocumulus or altocumulus clouds displaying an undulating, rippling pattern similar in appearance to fish scales; this is caused by high altitude atmospheric waves."
"It is sometimes known as a buttermilk sky, particularly when in the early cirrocumulus stage, in reference to the clouds' "curdled" appearance."
