That is correct for antelope......average fee $350 - $400. I suppose the "quite a bit more" for deer would amount to $800 and up.
No doubt, you can hunt deer and antelope in Wyoming every year if you've got enough money. These private land units with lots of left over tags are selling most of their tags. Check the Wyoming Game Dept. left over list now. A few tags left but, not many. So, seems there are enough guys with pocket money to pay the land owners what they want. And, they are comeing back yearly once they find a place that will let them hunt. It is a money game in those private land units.
I've been looking around Gillette as well. Same deal in Unit 23. Lots of antelope, lots of left over tags, very poor public access and substantial fees for access to private land.
I would like to mention, the land owner lists I have requested from the Game Dept for the Sheridan Region and the land owner list I have recieved from the Sheridan and Gillette chamber of commerce are the same lists. I have googled a lot of the ranchers and found the lists very out of date. Lots of deceased, many are now hooked up with outfitters. I did find a few with past or pending legal issues for game violations and enviromental violations relating to drilling waste disposal. That was interesting. But, the point being, those lists probably haven't been updated for years.
