Red sky at night; shepherds delight

After spending ages trying to round up the herd of exmoor ponies and getting them all wormed I walked back to the car and noticed how beautiful the sky was. It always makes me think of the rhyme:

'red sky at night;shepherds delight,
red sky in the morning; shepherds warning'.

I thought it was quite fitting that as Id finished "shepherding" the ponies round the hills the sky smiled with me at a job well done.
