If you think it's bad now you should have smelt it 40 odd years ago; if you drove past on the main road and the wind was blowing in your direction the sulphurous smell nearly took your nose hairs out, or it seemed like that when I was a kid in the back of the family car on the way to Wales (the M56 stopped at about Frodsham in those days!)!
I like the photo by the way, it's one of those where the more you look, the more you can see, but the more lost in it all you get!
