What Happened?

According to the 1900 census St. Louis was the 4th largest city in the United States. It was in fact such a highly considered place that the 1904 World's Fair and Olympics were held there.

Just a little over a hundred years later St. Louis isn't even in the top 50 most populated cities in the country, it's the "most dangerous" and we still talk about that god damn World's Fair as if we had something to do with it.

Apparently something happened to get the city where it is today. Probably a lot of things happened.

I'm currently writing an article and doing some interviews about what caused the downfall of St. Louis.

I know no one is reading this yet but if anyone stumbles on this blog feel free to comment.
I'm eager to hear what you think did the city in.
