I have hunted in 3 times over the last 4 years. It is an interesting unit. Even if you had time to scout you could not. Non-members are not allowed into D unless they are hunting white tail and then you can only be in there 3 days before the hunt. If you have never been hunting in D I would recommend going with a guide, they will usually work you out a reasonable deal. I have had experience with a couple of different guides. I have hunted with Dewey Wesley. He is a class act, just depends on if he has availability. I have spoken to Hoss (on this forum) on the phone, he appears to be a class act as well and seems to be honest and doesn't hype it up like some. I have had a bad experience with one guide, Gabriel Jackson (turnbull guide service). Be careful of him, that's all I will say on that one. It is difficult to kill something over 100 inches in the unit, but it is possible. I have hunted typically the entire season all years, give or take a day or two. The southwest corner of the unit is popular and for good reasons, you'll probably want to spend a bit of time in that area. The unit is enormous and deer are found from one end to the other. They are not in every canyon though, but tend to be in small pockets. Knowing the unit pretty well, If you don't go with a guide, I would expect you'll have a pretty tough hunt and will probably not want to go back.
