It's been years since I have been down there, but getting permission to hunt some private land is key. We used to run into them all over out there in the late 90s during deer season (I have some pictures-ill post them if I can find them-pretty cool to see a bull elk in the middle of a burnt out wheat field).
There are farmers that want them gone, and others who want them there. If you can get a spot, really the only way to hunt that area is to get some elevation, sit tight and glass, and hope something comes your way. You will push animals around if you are driving out there, and unless you have permission to hunt on multiple adjoining farms, you won't get close enough for a shot. Bring your coyote gun, you will get action if you are patient. Also, you probably know this already, but the farms are not delineated by fences out there, you can easily trespass unless you know the ground well. Good luck.
