Dillon you will find that in Eastern Wy, it will be very easy to get free or real cheap trespass access to those private ranches for antelope hunting. Just start knocking on doors and ask. Deer will be more on trespass fees, but you can get lucky there also.
I use to hunt antelope area #11 and filled many tags on a ranch there on 3 different hunts. The original ranch owner passed away and his son in law took over and got greedy and allowed the ranch to get shot out for both deer and antelope by over hunting it and charging higher fees.
Used to be a great game animal processing plant in Douglas that made great sausage from the antelope meat and did excellent wild game processing at a reasonable price. How it is now, I do not know as I have not been back there for about 10 years.
When you get back there, find the game warden for the area and he should be able to give you some good leads where to go knocking on doors for trespassing at a reasonable cost.
