My great grandparents were residents of Dodge City, and when I was a kid there were many stories about ghosts in various places in the city! I thought Boothill was just another place to play, but I was 8 years old and tourism wasn't so big then!
I basically think of Dodge City as a small dying Midwestern tourist trap with friendly people worth a one day visit if you're in the area, similar to Tombstone, AZ.
I've only been through on the Chief in recent years and its usually dark, so can't say for sure how it is today!
