Re: Blue Moon
To be honest, I didn't know where the phrase "once in a blue moon" came from, but now I know, so thanks for the link Mags.
There are so many song titles attributed to this unusual phenomenon and I know this isn't the Music Section, but how many songs can you think of:
Blue Moon of Kentucky, for starters!
I have seen yellow moons, orange moons and pink moons but like Marian, I'm no good a photographing the moon, so I've never captured one.
