When I met my wife she took me to a wonderful restaurant in a tiny village on the Alps near where she lived at the time, from which you can see the planes (the Pianura Padana) down below.

It was a beautiful, clear day, you could see for miles.

Then while taking in the view I noticed something like a disk of yellow fog in the distance, nasty looking and so thick you couldn’t see what was underneath.

It really stood out, as it was the only blemish in an otherwise spectacular vista.

“Ew what’s that?”

“Milan” .

If people could see how it looks like from above they would never live there.

Last time I had to pass through I could feel the particles of smog on my tongue.
