There’s a wildfire spreading across the rough Missouri River breaks on the Smikle Ranch north of Herrick, South Dakota. No smoke, no flashing lights. Not the kind of wildfire you’d expect from an out-of-control burn or even a forest fire. It’s a wildfire-like spread of knowledge, and Jon Smikle is fanning the flames of it. So far, it’s caught on with his wife Abby, his two sons, and his hired man.
