“I am guessing somewhere in DTLA on a Sunday due to light traffic. Lack of smog is another clue.”
It was downtown LA, as I could read a couple of the street signs. Other clues were the relatively tall buildings and frequent buses. Could have been Sunday, but the air clears up, even today, in that part of LA, during the afternoon.
If you go further east, maybe 30 miles, you get the worst air the country had ever seen. And it was at that time, due to mainly to cars and industry. Today the cars are far, far, cleaner (by a factor of about 100), and must of the industry was kicked out.
I was born and raised in LA, the west san fernando valley, smog in the 1960’s was horrid, so thick you could use a knife to cut it. hurt to breath some times..
