Colorado is loaded with cattle and sheep ranches. They do NOT want to have to defend their herds from wolves.
There is a wolf sanctuary on the front range and I can guarentee that when one of them gets loose, the people get very upset.
The ulterior motive is for the wolves to kill most of the game, like deer, elk and moose, so you either become dependent on the goober mint supply of meat, or starve to death.
