The Minnesota State Fair midway has been the amusement park area of the state fair for at least 40 plus years. I’ve lived here my entire life. Machinery row and the ag buildings has/have most of what you’re talking about, and to the best of my knowledge, minus the tractor pulls, which are likely held in the outdoor arena/stadium if at all.
The Illinois State Fair had a midway park area as well. I don’t know if they still do. There seems to be fewer traveling amusement parks than there used to. Perhaps they couldn’t keep up with Six Flags etc. You wonder if it attracts the wrong crowd it might be better to drop.
