Thanks for laying this out. “The hill to die on“
Which in Utah might be a problem (or is it another state, I don't remember)
Hoo else could ya mean then https://en.wikipedia.org/wiki/Hoodoo_(geology) (beautiful state! see hoodoo pics)

Kansas, but Google says the flattest is Florida (surprisingly - or maybe not)
