Pink Sky At Night...

I don't often have time to appreciate the sunset, but every once in a while I look up and I'm blown away.  Last night I saw the most beautiful pink sky.  Pity I didn't have a camera with me.  Kind of reminded me of what my mom used to say... "Pink sky at night, Shepherd's delight".  Whether it's polution or not, it's beautiful.  Reminded me a little of the sunset last year, on old year's eve (ok minus the mountain and the sea, but you catch my drift):

I wonder what that old saying means?  Hopefully a sign of good things to come?
