Wide Wednesday . . . Sky

Sky is such a small word to describe what I observed today.  I have never consciously used the sky as the subject of a photo.  The exception are sunsets and sunrises.  Today I kept taking shots throughout the day and in the end it was hard to choose.  I have gone for this one because it is blue and 
green. That's my hill again.  The day looks warmer than it was.  There was a chilly wind from the south.  This morning there was heavy cloud cover. Mid day and the cloud had almost gone and then this was just before 3 pm and the clouds were coming back.  
Thanks to Steveng for hosting while Bob is in sunny Crete.
