Fairly often and I'm not from Chicago. If I could time travel, 1893 would be on my short list of destinations because of the Chicago world fair.

Another one would be 1851, the year of the first world fair in London. The old fairs would already be awesome for a modern visitor, but I can't imagine what the people living then must have felt, seeing things like electricity for the first time.

I can't visit them, but I did at least dedicate 2 chapters of my game to the 1851 one: https://store.steampowered.com/app/3040110/Outsider/

As a Chicagoan... quite often. So many things were introduced there, it's not hard to find a reference with some regularity.

It's disappointing that the two promised movies around the events of Devil in the White City still have not come to pass. One was supposed to feature Tom Cruise in the role of Holmes, and the other Leonardo diCaprio.
