I have hunted Unit 4 for elk. It was only once about 6 years ago on a Ranching For Wildlife tag on the 4 Mile Ranch. Lots of NF in the middle of the unit. The area we hunted was on the western edge of the unit. Lots of elk in the unit, but hunting can be difficult. Once you get the info you need on the PP you are going to hunt, send me a PM and I might be able to help some.
