I started to hunt Colorado as a NR about 8 years ago and the OTC bull tags were around 500. They will be around 600 next year and I don't think that is too excessive considering the small steps they have gone up every year. I have hunted in several states and a few Canadian Provinces and rising NR tag fees are common. IMO Colorado has done it right but have to be aware of some of the other western states who went too far too fast. There is a point where the average person will not go out of state hunting if the fees get too high. Most Fish and Wildlife Departments rely on license sales to keep even with expenses and maintain habitat. The NR sales are important.
