Prices at the Iowa State Fair are going up. KCCI has a story (not embeddable), including an interview with a major concessionaire who says prices are going up 50 cents to $1.
Perhaps the first sign of this was last year, when the pork strip basket I raved about in 2019 was $2 more in 2021 (and had less dramatic presentation).
Admission at the gate is $14, with advance tickets for $9, not half price like they were a few years ago. I suspect that could go up next year too.
