Unknown setting

So Sunday my writing group did an exercise for writing setting. I tend to struggle with writing setting. When I read, I tend to let much of setting details float by. I think setting is often times used pointlessly, or simplistically. It's purpose is often times to do little else but to paint a literal image in the reader's mind. But I tend to base the images off of personality or atmosphere, and memories much more than I do off descriptions. When the description serves more than one purpose, It sticks with me better. for example, when I read about Jim Butcher's character Waldo Butter's jet black hair, I remember it, but I don't visualize him that way. I visualize him as having dirty blonde hair. But when Patrick Rothfuss talks about his character with red hair, bright red, red as flame.  I remember, the image is powerful, it's brought up many times, and it is woven into the story. it's important. Now, Butters is a side character, and there can't always be importance to hair. Yet character description is demanded by the readers..... Long story short, because I often times ignore descriptions when I read, I tend to forget about descriptions, or forget the details of descriptions when i write. So practicing this was especially needed by me.

In the prompt, each of us was given a popsicle stick with a name of a setting, steam punk, ancient Japan, post apocalyptic, Egyptian, USA in the 1920s, etc. I wont give mine away, but I knew very little about it. We were also supposed to describe it as a tour guide, but by the time i'd wiki'd my subject, I'd forgotten that detail.

In entering the section of the city I call home, I always finds myself with
mixed emotions. The world isn't what it was expected, the last great war
had ended, it was supposed to end all wars. In those sections of the city
soldiers danced in celebration of the end of wars. In my city, there was a
new war, a younger war.
There was progress too. 3 sky scrapers fought for dominance of the sky,
two twins and a younger brother. It's one of my favorite sights. depending
on the angle, the towers looked both complete and in progress. construction
Workers toiled to finish, and desk jockeys rode elevators to offices.
And then there was our leadership. "I am not a crook" played on every screen
was echoed in mocking by small children. No things weren't perfect. The
ideology of uninhibited love of the previous decade had faded, and was fading.

I think that came out pretty decent actually. Can you guess my setting? 1970's America.
anyway, gonna try to work up the motivation to write some novel now.
