The late Palouse tag is a great tag! I've hunted that area and as many others have said it's almost all private land. In addition, some of the farmers have gone to charging an access fee to hunt their land. I would suggest making the rounds this summer and checking in with farmers in the Palouse. If you live close, you may even want to offer to trade some work during harvest, maybe trade firewood or even trade hunts or a fishing trip. Sometimes just the offer will separate you from the many hunters who are trying to access their land. Just something to think about. Good luck with the hunt!
