I recommend Louis Terkla's "Hunting Black-Tailed Deer" and Boyd Iverson's "Blacktail Trophy Tactics" for checking all aspects of your hunting method. John Higley's book on northern California blacktails has excellent tips on still-hunting them. With blacktailed deer, you cannot be too careful or too detail-oriented. They are, quite simply, very hard to hunt.
You're hunting very difficult areas. Look at the harvest reports. Naches is worst in the state. Green water - 653 side? - that unit sucks.
