The entire 175 Lick Creek unit is open for that hunt, and it's pretty much all huntable public land. Don't think the whitetails are only in the farm country, and don't think they'll migrate out of the snow down to the farm country. Those deer are different there. The biggest whitetail I've ever seen alive was in the national forest in the Lick Creek GMU, late November at close to 5k' in a couple feet of snow.
My buddy has the West Blue MT foothills muzzle tag and he has been all over the hills from Walla Walla, Dayton, Waitsburg, and Prescott. He has seen a few bucks but none with doe's and no rut activity at all as far as he can tell. Seen a lot of doe's but no bucks with them.
