Unit 21 has a lot of elk in it, very large area. They are spread out though. The bulls are not huge since it is an open area. I grew up in unit 21, hunted many game there as well. Some of the lower elevation holds small groups of elk all year long. There is some private land so be sure to have a BLM map since most of the PL will not be posted as such. I will try to answer as many questions as I can.
