One of the stranger aspects of ATV use- and I've spent most of my life in elk country, often hunting public land- is that, if you were trying to design a machine for the purpose of spooking elk, it would look, sound & smell like an ATV. The reason their use isn't even MORE restricted, I think, is that the
goal of hunting in CO is not to harvest game. The goal is collecting revenue. As long as ATVs are used within the stated laws, the state is perfectly pleased to have more hunters unsuccessful, as long as more licenses are sold. It's the licenses that are sold that matters, nothing else. Can't blame anybody for doing what the state is selling.
