A saloon in the micro town of Bliss, ID has held a rock chuck derby annually for years as a fund raiser for worthy events. I heard rumors that they've cancelled it for next year because of rampant cheating. It's judged by the average size of the chucks shot and they have some pretty nice prizes. Some competitors have been bringing in dead chucks from elsewhere, spoiling it for everyone. It wouldn't surprise me to hear that some of the chucks have been weighted with sinkers, too.
