I grew up shooting them around Laramie. There are plenty to shoot but can be a little call shy unless you get private land. The mountains are full of them. The river bottoms are great if you can gain some permission. The base of sheep mountain would be a good place to start this time of year if your interested in hiking. I would also look at the public around the plains lakes. If Warren Livestock will give you permission, their land is great. They were based out of Cheyenne last I knew- they own a good chunk of the mountain between Laramie and Cheyenne. I would also talk to landowners in the Bosler area... tons of dogs out that way. Send me a PM if you need more info.
