No smoke without fire

Today's aim was to take a photo of anything, but not the power station or sunset. It was foggy all day, but turned out ok in the evening, so I thought I'd take a detour on my way home and pointed the camera at the view; at the trees and fields and rolling countryside.

Then this happened behind me. I did my best to ignore it, but after a passer by went out of his way to rush over and tell me how amazing the sunset looked behind the cooling towers I gave in. And this is it.
