If I could return in time to any one Abe the, it would probably be the 1904 World’s Fair in St. Louis, Missouri.
I could go on and on about this event but instead, refer those interested to two particular sites.
Lee Gaskin has a marvelous website that anyone interested in this particular world’s fair would find hours of delight.
On Facebook there is the 1904 World’s Fair Appreciation Society.
Another fascinating site is http://1904worldsfairsociety.org/site/
Here are some photos of the fair, also know as The Louisiana Purchase Exposition. I especially love the ones with people in the photos so you can get a grasp of just how large these palaces were.
