I've never had too much problem finding places to hunt around Pullman/Colfax. Try wearing a pair of jeans, a WSU shirt, boots and carry a pair of gloves and pliers. When asking for permission, start off by asking if they have any fences that need mending. If they say no, just tell them thanks and that you were looking for a place to hunt in return for some work. Be prepared to spend a full day or two though!
