Best Rodeo for Rodeo-Obsessed Kid

TL;DR: What rodeos would you recommend for a ~6 y.o. to make a big trip really worth it? What are the different 'vibes' of various rodeos? Bonus points if it can be easily combined with a national park!

My kid has been obsessed with rodeos for a while now, and if it keeps up, I'm considering trying to organize a holiday in the next year or two that focuses on going to a really good one... ideally alongside a national park or two.

I'm easily finding discussions about the 'best rodeos', but it's hard to get an idea of the 'feel' or vibe of the different rodeos. (E.g., how touristy, how kid-friendly, just how insane in terms of size, etc.)

We often focus our holidays around national parks, so I'd ideally love to combine that. I've thought about the rodeo in Deadwood, for example, to then go to Wind Cave and Badlands.

Thanks in advance for any recommendations!
