If you were reading the Bird, that must have been Hotlanta in the 1970s.
She probably hadn't done any travelling other than Wyoming communities in the same region, such as Caspar. But I find it difficult to impossible to believe that a 19-year-old in the early 1980s would never have watched television and never heard the word "gay" used in a sexual orientation context on TV at least. Riverton might not be a metropolis, but it isn't an Amish community or a monastary. From your account, it sounds like you at least knew what the word 'gay' meant by the 1970s and I expect Alma Jr did too, even if she didn't know many details.
You do have a point there since I lived in a small city in the south and I had heard of the word. I didn't exactly know what it all meant, but I had a feeling it had something to do with me. And of course I was familiar with television and even then there were episodes of shows or movies that dealt with the subject. I remember a show called "Family" that had an episode where the son had a friend that came to visit who was gay. I loved that episode. I wish I knew where I could find it now since I would like to see it and see what I thought of it now. There was also a movie where this boy was visiting his father in San Francisco (I remember the cable cars
). The father had a male lover and the boy was all upset. I'm not sure what the name of the movie was. And then of course there were the questionable music groups and singers such as Elton John, David Bowie, etc. So in thinking more about it I can see that Alma Jr. would have had to at least known of "gay" issues.
So you know of "The Bird?" At that point in time I considered Atlanta the biggest city in the world
And what is funny is that there are many people here that still consider Atlanta and Charlotte as the biggest cities in the world. Back then Charlotte was nowhere near as large as it is now. However, of course, neither are that big when you compare them to other places. Many people here don't do a lot of travel. Some have never left the county
In fact some from the outlying areas consider Asheville to be "the big city." I had culture shock the first time I visited my sister in Houston
I've come a long way since I can now visit and walk through New York City by myself
