Are you really that much of a moron? Just because a tag ALLOWS you to hunt on public land does not mean it was USED on public land. The vast majority of elk taken on private land in CO are taken with regular OTC or draw tags, but where the hunter has paid a trespass fee (either directly, or through their outfitter) to hunt private land.

The success rate for DIY public land hunts is minuscule We can argue whether it's 2% or 3% or 4% (Wyoming is right in the same range), and it varies by year, but it's so small as to be effectively zero. Parks and Wildlife likes those beautiful out of state checks so much they do everything the can to hide it and mix DIY failure with private land and outfitted success though.

Incidentally, New Mexico has a decent success rate for DIY hunts and far superior herd management so there are actually some elk, but good luck drawing... and no OTC of course.
