In states like Arizona, New Mexico, Colorado, Utah, and Wyoming that have numerous units with very limited entry archery hunting, there is some great sage/juniper elk hunting in certain units. Since Oregon has very few units with highly limited elk hunting, I think your search is gonna be kinda difficult in this state. Wagontire I realize has some good harvest stats, but I believe most of those elk are coming out of a very small area, and I believe mostly on private.
