As a musician, the first thing that comes to mind when I hear the word "key" is the keys on an instrument or the key in which a piece or music is written...playing Beethoven's Moonlight Sonata in the key of C# minor on the 88 keys of the piano is also a key to happiness.  Throw in a good book, a key to imagination, and unlock the makings of a perfect afternoon!

What do you think of when you hear the word "key?"  Is it the keys to your home?  Elusive car keys?  The key to your heart?  Or keys to your happiness?  Or, keys to success?  Whatever it is, photograph it!
