From Pittsburgh l, grew up across the river from a coke plant. If you've read an article on US Steel being sold recently it's likely got stock footage from the plant.
But it never stops. These facilties run 24/7. In fact a lot of the ovens can break if they're not running.
And then there's the fact that the hills bottle things in (PGH sits at the base of the Appalachians). It gets really bad when there is a temperature inversion over the area.
It's not as bad as it used to be though. Dad's generation always talked of how the snow would be dirty after a few hours, which I don't really see.
Geo fencing is only one layer of defense. It's necessary and useful to some degree, but it should be a part of a whole system. It's place in the system is literally that of a fence.
The most sensitive places are going to need some active form of defense. There are fiber optic drones, good luck even trying to scramble them.
I went to a private high school in the US and graduated in 06, just to set the scene.
Animal Farm was on the reading list sophomore year, and you were tested on it strictly on the plot. What happened. Who did what. That's it.
The class as a whole learned more about cheating than anything, because the teacher used the same tests for his whole career. They were typed on a typwriter, you just wrote your answers on your own paper and turned them both in. He was a good basketball coach from what I understand though, so... yeah.
This graces the cover of one of my playlists and it cracks me up everytime I see it.
