Idaho's been doing this for years. In all hunts with quotas or draws, non-res applicants can only get 10% of the tags.
UP to ten percent of the tags. Oftentimes it’s less than that.
In draw hunts, they just start drawing at random. When or if 10% of the total tags are drawn by non-res, the rest are skipped if their name comes up. In hunts with very few tags and lots of applicants, it's very possible that no non-res will be drawn before all the tags are gone.
