Chad,
I harvested 3 antelope in this area last year on public. The public land is very limited and I have already sent a couple of guys to the land I am aware of. Would hate to have you guys stepping on each others toes... My recommendation would be to wait about a week into season and then go. Since you aren't hunting bucks there isn't any reason to be a part of the chaos that is opening weekend. Contact the Laramie Wyoming Game and Fish office for a list of landowners. There are some that allow hunting and others that charge a trespass fee. Also, there should be hunter management areas available later in the season for you to hunt on. It would also benefit you to talk to the local warden as he may have information that the office doesn't have.
Please head over to the new members section and introduce yourself. Lots of nice people on here sharing great stuff... would love to have you contribute.
