A steamy sunset.

I was looking after our Granddaughter when she finished school tonight, at her house. The house has a wonderful view, over the Team Valley Trading Estate, and beyond, to the Ravensworth countryside.
Tonight it was dark, wet, and windy, but when I looked out of the window, there was a beautiful, pink sky. However from one of the factories on the Estate, were huge clouds of steam. It seemed to go up into the sky to join the clouds, and the pink colour soon disappeared.
