My wife and I owned Signe's Restaurant in Casper back in 1989 and I worked out at the Amoco Oil Refinery. I hunted all over the state for Pronghorn, Mule Deer, and Elk. If you contact ranchers and work with them you can find some fantastic places to hunt but you have to be willing to do some ranch chores to get in good with them. I hunted places few ever saw because I grew up country and understood how to treat people and their property!
Treat everyone like family and like their property is your families' property made out of gold. Do that and you will be amazed what will open up to you.
