Think that is what Joe is joking about.
I'm not in London,60 miles away in the Midlands.
The old smog problem was sorted out with the 'clean air act' back in the '60s.
You still can't beat the week long freezing fogs, they produce a really pretty winter scene.
Good night. :)
And everyone missed my quip about the man eating fog.
*sigh*
Whenever we get thick fog here in NY, people vanish.
It’s almost a given.
Usually they get found hours later sitting in a wrecked vehicle whimpering about life.
Usually.
A freezing fog has the “Skin biting” quality to it that makes it much more miserable to deal with.
