There is a world of history to be savored by researching the world's fairs, such as the 1904 St. Louis fair, and the one in Chicago 1893. Here is a link for a grandmother's story of how she visited the fair in St. Louis when she was six: http://washingtonmo.com/1904/midi/stuartg.htm
When she was six, she was looking into a future of improved lifestyles, enriched by electric appliances and an invention that re-wired peoples' brains: ice cream. My own grandmother spoke often and awestruck of her introduction to it. And she always added, Don't eat too much of it or your rearend will be huge. Which, I found, to be accurate.
We can look backwards 106 years later and realize most of the modern wonders seen at the World's Fair for the first time and taken for granted or taken for entitlements now, aren't really any good for us. And they don't make us happy. And we don't appreciate them. And we're trying to learn to live without them now, so we won't use up all the earth's resources.
There were massive, intricate structures built just for the fair in St. Louis, and had to be torn down afterwards, for the most part. The story with all its details is just captivating.
I began to wonder what things I'm doing now that will be thrown into the dump and laughed at a hundred years from now. Or even sooner!
