I'm not a Wyo. resident nor have hunted there.
However I make the drive to Colo. from Utah quite often (I was born in Loveland), and I see antelope quite often from I-80 from Evanston all the way to Laramie. I know that there is alot of BLM land in that area , and would think one could do well just about anywhere in that area.
Good hunting if you get your tag.
