Or maybe the 20% rule? That's from a few years ago when they decided to lower the NR tag quotas for hunts which take more than 5 years for CO residents to draw................or something like that.
At that time it was the death knell for those of us already desperately chasing a better unit. It completely took away a unit 61 tag which I could have drawn prior to that. There are massive numbers of NR high point holders floundering around for anything now.
