It all comes down to basic deer hunting. The only problem is that this is very difficult, even though the basic premise is simple. Good cover is essential, especially if you consider scent control as part of the cover. As you know being still is a major factor as well. The trick is finding where the deer wants to and setting up in such a way that you are hidden and the wind is favorable and you still have a good shot angle. In addition to cover in front of you, don't forget having a cover screen behind you. Yes, you learned all of this in the first book or video that on the subject of deer hunting. In short do these things: find a good location, sit down and point your nose into the wind, BE STILL. Finally, pick a spot. Even with all these basic hunting habits, pray for a bit of luck. Ground hunting has always been very challenging, and in those areas of heavy hunting pressure, educated deer are adept at checking out the trees. Actually it sounds like you are basically doing most of the right things, so it is just a matter of time. Remember, in trad bowhunting, the odds favor the deer. That is what makes it so much fun.
