For blacktails I'd just recommend hunting as close to where you live as possible. Find some private property and get permission to hunt it, or look for public land spots that rarely get hunted, either because it's too far for most people to hike to, or because it's so close to the pavement that everyone ignores it. If you concentrate on hunting areas that are close to home, you can scout more often, which is the key to success. It's either that or you could do the Vail road hunt along with everyone else, and kill a little spike from the road in a clearcut. As for muleys, look at Okanogan and Chelan counties.
